5.25v? Do you mean 1.525? Are you using any torture testing programs to check stability? So, your idle temps are 45C CPU and 25C mobo? "So I have that going for me....Which is nice"

LoL. sorry. Right 1.525v and 45-50º cpu & mobo 45-55º. Now i'm running at 2.651.5ghz (241x11) 1.525v anyway. HT: 964mhz, Memory 400mhz ddr. WinXP professional SP2 DFI Lanparty nf4 ultra-D AMD 3700+ San Diego 1gb+512 pc3200 eVGA 7900GTO 512mb WDigital 160gb sata WDigital 250gb sata

I havent check stability with any program, i'll do it as soon as possible. thanks WinXP professional SP2 DFI Lanparty nf4 ultra-D AMD 3700+ San Diego 1gb+512 pc3200 eVGA 7900GTO 512mb WDigital 160gb sata WDigital 250gb sata

I am going to test 275*10 this weekend. I have some good thermal compound on the way. I plan on lapping the hs and cpu and using the compound. I am hoping it will drop my temps 3C-4C. If so, I will be just over 60C core, 52C-3C CPU and 45C mobo. I'll let you know how it goes.

jdiesel, 1/2 multiplier settings are not "officially" supported by the A64. Set your multi to either 11x or 10x, but not 10.5x. If you have the CPU Freq set to 275MHz, what speed is the RAM running at? If you have to set the BIOS to DDR266 & run it at approx 183MHz, you're sacrificing RAM bandwidth.

I am not sure. I ran the OCCT test with it set to 100 to check the CPU alone. When I run at 166, it shows the multiplier at either CPU/14 or CPU/13 in cpuz. The RAM is the reason I was using the 10.5 (runs it at 201). I am going to do more testing this weekend to see if I can get a stable 2700 or more somehow. It seems that I need to raise the voltage quite a bit to get stability. I am starting to think this stepping is garbage. Hard to tell since I am new to this and it could be all me, lol. I just started trying different bus speeds with a x10. I am pretty sure I can run 270 or 275 stable. I will post what the ram speed is when I get home.

Use the same settings that I recommended above. 11 x 250MHz w/RAM at DDR333 & HT multi at 4x. Adjust the voltages as necessary. Remember, there is no FSB, so you don't necessarily have to shoot for the highest CPU Freq. Ideally, you want the HyperTransport bus to run at 1000MHz (or as close as possible without going over), the CPU running at the highest possible clock speed, & the RAM running at 200MHz (at least). The A64 benefits from tighter RAM timings too 2.5-3-3-11 is most often recommeded at 1T. I have an overclocked S754 A64 3000+ Venice (2.0GHz @ 2.5GHz) & nForce3 250Gb board, so my settings are a little different than yours, but I had no problem running it at 2.7GHz (9 x 300MHz) during testing. Have a look: http://i68.photobucket.com/albums/i... Did you ever get the 1T/2T issued straightened out? What about Spread Spectrum?

Finally i think i found optimal settings: CPU core: 2.5ghz - HT link: 1000mhz -Memory 415mhz DDR. CPU temp: 40-44º iddle - mobo 48-51º iddle. I changed: DRAM frequency Set: 166 FSB Bus Frequency: 250 LDT/FSB Bus Frequency Ratio: 4x CPU/FSB Bus Frequency Ratio: 10x CPU VID Control: 1.45v http://www.hardcoreware.net/reviews...

"CPU/FSB Bus Frequency Ratio: 10x" Change it to 11x...if necessary, raise the voltage. And double check those temps. It's almost impossible for the board to be hotter than the CPU, unless you mixed them up? Try this program: http://www.thecoolest.zerobrains.co...

Well, the thing is that my 7900GTO is BIG, really BIG and encumbers to the mobo fan, so the mobo has an airflow issue. I used to have the video card in the pci-express slot2 but that slot runs the video card at 2x according to 3dmark06. i increased 25% result by changing to the other slot. By the way, i tried the values again but sudden restarts i tried from 1.45v to 1.55v :( I dont know why in the afternoon ran well, but kind of hot. Am i losing a benefit by lowering to 10x?

I tried 300*9 last night. It was OCCT stable for the 1/2 hour test with vcore at 1.46. I then tried prime95 and it only lasted 25 mins or so. I set the vcore to 1.49 and started it today before I left the house. My max cpu temp was @ 49C and core temp @ 63C. I am pretty sure that my RAM was running aroung 195 when set to 133 and 225 when set to 166. I still haven't figures out a was to disable spread spectrum or command rate. I am going to try 275*10 and 250*11 tonite. I am hoping that if I can drop the heat a little, these settings will stablize. I don't want to raise the vcore past 1.55. My other problem is that I haven't been logging my settings and results. I need to start so I can see what works.

"My max cpu temp was @ 49C and core temp @ 63C." Why not replace the stock heatsink with better ones like thermaltake big typhoon, scythe ninja or the zalman cnps9500/9700 along with arctic siliver 5?

It's all about compromise. The problem with 275MHz is it will force you to run the RAM too slow (or too high), so what you may gain in CPU speed, you'll either lose in memory bandwidth or memory stability....plus you'll have to run the HyperTransport bus at 825MHz (3 x 275). It's generally not recommended to exceed 1000MHz, but you *may* be able go slightly higher with no ill effects...4 x 260MHz (1040MHz) for example. 1100MHz (4 x 275) is pushing the limit. A quick test to check your settings is SuperPi. Everytime you make a change, run the 1M test to see if the time improves or not. The newest versions show the time in millieseconds so you'll be able to detect the slightest change in performance. My time is about 37 secs...your's should be better. http://www.overclock.net/downloads/...

My best so far is 36sec. The more I read acout this particular stepping, the worse it looks. To get past 2.7, people are saying they need to really up the voltage. I was thinking of buying a 4000+ on newegg for $80. I should get a better chip and will be able to sell this one for $50. The difference would be the same as an aftermarket cooler. (plus, I wouldn't have to push the chip) It all depends on how good the 4000+ is. I haven't reied anything higher than 1000 for htt. I am hoping I am still running prime95 when I get home. If so, I am going to lap the cpu and heatsink which should get my temps down a few degrees and keep it stable.

jdiesel, I think courtesy demands that you start your own thread - rather than hijacking LiON200x's. How To Ask Questions The Smart Way

Why would you spend $80 for another CPU? It's the same core! A San Diego is a San Diego...the only difference is the 3700+ has an 11x multi, the 4000+ has a 12x multi. That's it! Chances are it's not gonna overclock any better. If you check the specs, you'll see they both have E6 stepping. IMO, getting the 4000+ would be a total waste of money. http://www.amdcompare.com/us-en/des... http://www.amdcompare.com/us-en/des...

Since all desktop CPUs arguably spend most of their lifetime in idle mode as opposed to actually doing some crunching. I don't think it is irrational to be content with whatever the most OC Mhz you can eke out of the CPU is - without commiting any supplemental dollars on aftermarket cooling components. You may or may not realize this, but in many instances when trying to overclock a CPU to absolute levels, it is not uncommon for the *true cost* of a faster (retail) CPU to be less or come up to about the same as the overall cost of the cheaper & lower priced CPU purchase with overclocking in mind. Stick with whatever you can get out what you've already bought & don't get carried away by what you think you may be getting away with now & how that can potentially be exploited some more with aftermarket components - the benefits from an overclock CPU is not residual in nature.
