Overclocking E7300

Gigabyte / Ep43-s3l

Specs: Microsoft Windows 7 Ultimate 64bit, 2.666 GHz / 4094 MB
Hello, I've bought my new computer 4 days ago, and I was thinking about overclock it. I'll try to ask all my questions at once, and provide the all info you guys may wanna need. Okay, so.. first of all, I've seen my CPU not being on working on 2,66ghz (except when cpu gets 80-90% of usage, then it increases itself). It was comming from an options in the BIOS, which I've disabled: cpu enhanced halt (c1e) and EIST. I don't really know if this gives better performance but still. So, I am running the cpu with the stock cooler. I was wondering if i can push it up to 3,00ghz and to be safe/stable. So, if you guys can tell me if it is going to be safe (or stable) and recommend me on how to exactly do the overclocking procedure, I'd appriciate it.

Also, I dont know if I can put this into this thread, but I want to overclock also the 9800GT (Palit) 512mb, cuz I've been told the cpu and the gpu and overclock good and stable so my performance would increase.

EIST aka speedstep when cpu is idle, speed, vcore, temp drop down.
There are settings u need to disable first. Read this
http://www.computing.net/answers/cp...

i assume u have ddr2 800 or 667. Underclock ram to 533 ddr then pump cpu freq to 333 (266 to 333) and reduce cpu multi to 9 (10 to 9) (333 x 9=3ghz). now ram should run at 667 ddr. Save settings and restart the system. If the system boot fine use prime95 to test if overclocking is stable.
if stable pump cpu freq to 400 1600fsb cpu mult 8 (400 x 8=3.2ghz) "ddr2 800 required"

edit: use EVGA PRECISION to overclock 9800gt.
Gpu clock=720
memory clock= 990
set gpu fan to run 100% all the time.

Yeah my ram is ddr2 800mhz, but i cant understand why should i underclock it? I was thinking 7,5x400 = 3,0ghz without touching the ram tho. I mean, would the performance increase if i do it like u said? And what about the shader clock on the video. Also, would it matter if i make 100% the fan of the gpu.

PS Sorry for writing in this thread, I just wanna ask something not related to oc cpu. Atm, with c1e and eist disabled default clocks on gpu-cpu I am having low fps on games such as Left 4 Dead. I mean what should i except from my system? When a lot of action is going on fps can drop to 30-40 depending on what's happening on the screen. Is it normal? By overclocking gpu and cpu (hope its stable) how would the performance increase?

cpu xternal speed and ram should run @ the same speed, ratio 1:1 cpu:ram. Before overclocking cpu u must make sure to maintain ratio 1:1. Then when u increase cpu freq automatic ram freq will increase. For eg. 333 x 9 ddr 667, 400 x 7.5 ddr 800 etc.
if u increase gpu clock automatic shader clock will also increase. When overclocking computer component temp increase, to elimanate overheating issues run gpu fan 100% all the time.
30-40 fps is playable for modern games.
with both cpu and gpu overclocked u can gain 10 fps.
Try (333 x 9) first.

Alright, I tired overclocking the way u said first, logged in windows, had system unstability. Tried my way (400 fsb, 7.5 multi) system failed to load. Maybe it has something to do with an option nearby the DRAM settings, i dont remember it it had 3 options: normal turbo extreme. In the description it said to run normal after overclock to improve system stability. I left it to turbo tho. Maybe the cpu cannot be overclocked or what...

When I logon to windows, I couldn't see my programs in the taskbar, couldnt propertise my computer, so I restarted, and defaulted it. I've read on the forums people with stock cooler can get it easily to 3ghz stable. Dunno what's wrong

When you increase the CPU frequency, you increase ALL frequencies...that's why you have to compensate by lowering the memory frequency BEFORE raising the CPU frequency. You also need to lock the PCIe frequency at 100MHz & the PCI frequency at 33MHz. EIST, C1E & all Spread Spectrum options should be disabled & you *may* have to increase the CPU voltage to stabilize the overclock.

The E7300 is a 1066MHz FSB CPU...that means the default frequency is 266MHz. Your RAM frequency should also be set to 266MHz (aka 533MHz DDR) to match the CPU. If you don't lower the RAM freq & then try to increase the CPU freq from 266MHz to 400MHz, the RAM speed will increase to 600MHz. There's no way your DDR2-800 is capable of running at that speed, therefore the system will become unbootable.

kuwese knows what he's talking about...try taking his advice. BTW, it would be easier to help if you'd list the motherboard make/model.

jam, I already provided info about my mobo: Gigabyte / Ep43-s3l. Well, I've first downclocked the memory to 266mhz, locked the PCI-E freq to 100mhz, saved, entered bios again, set the cpu fsb to 333 mhz x 9 multiplier = 3,0ghz. Booted to windows, I was just about to run OCCTPT and then I received a blue screen window and then system restarted. Maybe I shall give it up on overclocking, maybe the motherboard is weak or something... pity that people overclocked it to stable 3,0 => 3,33 ghz. I just dont wanna hurt the hardware.. Any suggestions?

"I already provided info about my mobo: Gigabyte / Ep43-s3l"

Most people include their system specs in the body of their post. I went back & double checked, didn't find it anywhere, then finally found it listed for the 'product' in the OP. Now that I know what it is, I'll download the manaul & review the BIOS chapter.

"Any suggestions?"

Sure, try increasing the CPU voltage. According to Intel, the safe range is 0.8500V-1.3625V. Find out what your CPU is currently running at & bump it up a bit.

did u try to increase cpu voltage?
Try to increase cpu frequency slowly e.g. the goal is to reach 333, so from 266 pump it to 280 save settings and check if it is stable, if not stable pump vcore (make sure to stay in range) jam already provide vcore safe range, increase 0.1v each time u increase vcore.

k, fixed that. So, ive ran the sytem no errors by now Vcore at 1,216 (at cpu-z) 1.25 at bios. 3200mhz overclocked. I didn't start the stress test by now, but im worried about the temps. I didnt see them in default settings , but now they are :
Temp1 : 42 C
TEmp2 : 32 C
Temp3 : -2C
Temp: 2C
Core 0: 54 C
Core 1: 50-51 C

So, what should I do?

i told u to underclock ram to 533ddr aka 266 not 667 ddr aka 333. Then pump cpu frequency. "Dram 499.5" i have already spot the problem.The problem is u overclock ram to 1000ddr aka 500mhz. U didn't lock pcie freq to 100 and we told u to stay in range 1.5v isn't safe (u need to follow instructions). There are settings u need to set first befor overclocking read response #8.

Yeah I already saw that. Currently I am running 333mhz fsb 1:1 ratio with the dram, multiplier x 9 a.k.a. 3ghz @ vcore 1,20 (1,8 default), pci-e locked 100mhz. Ran OCCTP it says it's stable. Temperatures are what is bothering me. Should I go more, or need to get better cooling before that, and are the temperatures ok? 42 cpu idle, 54C 51 C cores idle, 65-66C cores at full load, 52-4 C cpu at full load. And would there be any damage cuz I ran 1.5v for like 5 minutes, without any load?

yeah now your are talking, cpu temp are fine. I think 3ghz is fine but if u still want more u can increase cpu freq up to 400 1600fsb. Use the same method (from 333 to 400 increase slowly). Post the cpu temp when u reach 3.6ghz (400 x 9).
"I run 1.5v for 5 minutes" i think the chip is fine no need to worry.
Did u try to overclock 9800gt?

hey lostbg read your response #9.

Well, I want to make it stable @ 333 x 10, but last when I tried with vcore @ 1,25600 OCCT gave erros the first minutes. Maybe It needs more voltages. But I'll keep 3ghz until I get a better cooling. I am thinking to get Cooler Master Hyper Z600. Yeah I tried to overclock the card, but it is giving me artifacts with the settings u gave me. CPU Fan @ 100 doesn't change a single degree.

EDIT: ahah, yeah :P Well, it's cuz I was woried since I've spent my own money buying this crap. With my old ATI 9550 and mobile barton 2500+ default I was doing insane stuff, and it was like a rock, never burned the chip or whatever :))

try to reduce v-card memory clock. Post default clock for gpu, memory, shader.
I wouldn't suggest buying new cooler. 3ghz is fine plus u won't see huge improvement in games (3.0-3.6ghz)

stock clocks... core 600 memory 900 shader 1500.

EDIT: K, the problem must be comming from the core clock. I reduced it to 700, 990 memory, ran Furmark for 10 mins, didn't see any artifacts. Fan set to 100%. Now I have two questions. Temps. Idle - 45C, furmark loaded: 75C max
Q1: Is there any way I can go higher with the core clock, being stable..
Q2: Is setting fan to 100% making any problems (except the noise), or should I leave it auto?

P.S. I have a setting in the bios called Performance enhance, its in the memory section. Optiosn: Standart, Turbo(default), Extreme.

Since I have overclocked, and underclocked the RAM, at what setting should I leave that?

EDIT2: I haven't locked the PCI freq to 33mhz, cuz I haven't found such an option from the bios, what do you suggest?

Don't try to do 2 things at once...concentrate on the CPU/RAM & leave the video card alone. Once you get a stable overclock with the CPU, THEN worry about the card.

It's very important that you underclock the RAM, if you don't, you'll never get the CPU where you want it. That means that you'll have to play around with the (G)MCH Frequency Latch & System Memory Multiplier (SPD) settings until you can get the CPU:DRAM ratio at 1:1. You should be shooting for the CPU FSB at 1600MHz (400MHz frequency) & the RAM at 800MHz (400MHz frequency).

Temporarily set the CPU Clock Ratio as low as possible..6x? That way you can experiemnt with the FSB & RAM settings without worrying about ever over-overclocking the CPU. Once you get the Latch & SPD setting figured out, then drop back & start raising the CPU ratio again. See if you can get it to run stably at 3.2GHz (8 x 400MHz) with the RAM running in sync.

Remember your CPU voltage range. You seem to be concerned about having it at 1.25v...Intel specs the max safe voltage at 1.3625v so you have a LONG way to go. As for your temps, what program are you using? You don't think it's odd that you're getting readings of -2C & 2C? Check your temp readings in the BIOS.

I don't think u can go higher than 700 with stock cooling.

Yes the difference is small (gpu fan 100%) but i notice when u exit 3d application gpu temp drops quickly.

Gpu temp is fine

"perfomance enhance" i did a quick search and found better leave it to default (turbo). 12/8/8 standard/turbo/extreme the lower the better. Read this http://forums.anandtech.com/showthr...

okay guys, leave the overclock for a second something really bad happened today. Usually I run my PC 24/7, but last night i decided to shut it down, today when i woke up I couldn't boot the machine. I was like maybe my cpu f---ed up, went to a friend, checked all the parts and it was indeed the cpu. I thought its burned or i dont know, then i came back home put it again and i booted to windows. However the temperatures were 65C idle for cores. I changed the paste and the temperatures were dropped to 54-55C idle for core 0 and 49-50C for core 1. That's f---ing insane? I have intel box cooler, but the core temperatures seems to be f---ed up. I mean maybe my cpu is damaged? But even before the overclock the temperatures were that way aswell. I've read there shouldn't be difference with the core temperatures and they must be idling at 43-44-45C. So what should I do? I'm really woried.

At BIOS I cannot see the core temperatures. Only the CPU which is 42C. The thing is cores temp are running high. Yeah I am at default clock atm, temperatures are the same. Btw what was the problem causing the system failure which made me replug the cpu

There is nothing wrong with your CPU & nothing seriously wrong with your temps. Don't get paranoid on us. It's impossible to overheat a modern CPU to death. All CPUs (both AMD & Intel) have built in thermal protection circuitry...the CPU will shut itself down long before it has a chance to fry.

Overvolting it to death is a totally different issue. But as long as you stay within the recommended voltage limits, you should have no problems.

Since you apparently removed the heatsink & CPU, they MUST be thoroughly cleaned of ALL traces of the old thermal material, then a fresh layer applied. Do NOT re-use old paste! And when you apply new paste, make sure you do it correctly. For your CPU, use the "vertical line" method:
