Comment:
I'm having a crappy time trying to get my new cpu to work. My mobo is a MSI kt3-ultra... Yeah, i know everyone thinks it's crap, but its what I got... And it was free.
It had an athlon xp1800+ that was running perfectly fine, but i wanted to upgrade. I purchased the athlon 2600+ that runs 133/266fsb.
After initial installation, it said that it read as a 1700 running at 1.1ghz. I went into the setting and changed some things and the best I could get it up to was 1.47ghz.
I then updated the bios with the newest version available, but this still did not fix it.
I have also read the recommended setting for the cpu... but under the freq/volt settings I can only go to 220mhz fsb, 1.6v, and 15 on the multiplier. I havent changed anything under the ram.
Someone please helps, i almost ready to throw this thing out of the window!!!
If you have the 266MHz FSB version, check to see if there's a FSB jumper on the board...make sure it's set to 133MHz. Then go into the BIOS & set the CPU multi to AUTO & the FSB to 266. And make sure to run your RAM as PC2100 (DDR266), NOT PC2700 (DDR333).
Just to add, the 2600+/266MHz(133MHz) CPU has a default multiplier of 16x & the majority of those CPUs are locked. I don't see how you could arrive at 1.1GHz with a 16x multi, unless the FSB is running at approx 68MHz?? Also, it would not register as a 1700+ if it's running at 1.1GHz...it would have to be running at 1.467GHz (or close to it). Is it possible that you actually have a 1700+ & got ripped off? Did you check the model number of the CPU to confirm that it's actually a 2600+? (CPU labels can be changed by scam artists)
Yeah, i checked the model number on the cpu. Comes up as the 2600+ 133/266.
My mother board seems to be locked at an FSB maximum speed of 220. Now, i dont want to run it that high because it should be at 133, and be doubled through ddr... Right?
The maximum multiplier that I can set it to is 15. Will not go to 16, there isn't even an option.
Depending on the settings I have had it run at 700(something)mhz, 1.1ghz, and 1.47ghz. But it is still identified as a 1700+.
For the voltage setting, the maximum that I can set it to is 1.60v. Only reason I mention this is because most people recommend a setting of 1.65, but I cannot even set it to that.
The Bios update version 5.6 was "supposed to" offer xp2400 and xp2600 cpu support. I however updated the bios to version 5.7 assuming that the v5.6 info would already be added in the new one. Also didn't use the 5.6 because MSI says not to use older updates.
As for the ram, it has been running under 333mhz with no problem. Even with the older cpu. Do you think this could honestly be part of the problem? I think for the ram in the freq/volt settings I have it set to auto.
"The maximum multiplier that I can set it to is 15. Will not go to 16, there isn't even an option"
You have to set the multiplier to AUTO to get 16x!
"For the voltage setting, the maximum that I can set it to is 1.60v. Only reason I mention this is because most people recommend a setting of 1.65, but I cannot even set it to that"
You have to set the CPU voltage to AUTO to get 1.65v!
However, if you set the multi & voltage to AUTO & they default to something other than 16x & 1.65v, you do NOT have a 2600+ (unless you have the mobile version?)
"As for the ram, it has been running under 333mhz with no problem. Even with the older cpu. Do you think this could honestly be part of the problem?"
No, it's not part of THIS problem, but you're definitely losing performance by running the RAM at 166MHz (DDR333) & the CPU at 133MHz (266MHz DDR). With a socket A system, they should ALWAYS run at the same speed.
Still not quite right. After a little massaging I've got the cpu reading as a 2000+ and running at 1.67ghz. I left the fsb speed at 133 and changed the multiplier to 12.5. When I try and bump it to 14 or 15 the cpu speed goes down to like 763mhz.
Chip temp is reading 38c.
I still don't understand what the deal is.
Also, how do I turn down the RAM speed to match the cpu? I didnt see that option in my bios settings.
ok, bumped it to 166 and multiplier set to auto and voltage to 1.6v.... had to do that cause it crashed on first start up. Now it reads as a 2200+ at 1837.22mhz and temp at 40c.
I did notice that (i think) my jumpers allow for a 166 setting... But i'm not sure how to change it.
Anyhow...
advice is welcome... Really need help. Don't wanna blow it apart.
OK, you said you tried the CPU Ratio setting at AUTO like I suggested (freq at 166MHz) & the CPU speed was 1837MHz? That would mean the default multiplier is 11x. The only AXP with an 11x default multi is the 1700+. If you had a 2600+, the multi *should* have defaulted to 16x. But since your CPU is apparently unlocked, you can do just about anything you want with the ratio setting anyway.
Regardless, if your system runs stably at 166MHz (333FSB) & you're sure you have a 2600+, why not just clock it at 13 x 166MHz (2167MHz) & be done with it? Bump the CPU voltage (vcore) up to 1.70v just be be safe.
"how do I turn down the RAM speed to match the cpu? I didnt see that option in my bios settings"
Under Advanced Chipset Features, high-lite "DRAM Timing Control" & press ENTER...then go to "SDRAM Frequency" & change it from SPD to either 266MHz when using a 266MHz FSB (133MHz freq) CPU or 333MHz when using a 333MHz FSB (166MHz freq) CPU.
Ok, i saw that setting for the RAM and didn't realize that was it. Thanks!
As for running the cpu at 166x13, that won't happen. The highest voltage setting I can select is 1.60v. When I set the fsb @ 166 and multiplier at 11.5 it hangs up on start. Thats why I've got it sitting at 11. If I could up the voltage I would give it a try.
I guess I'm stuck where I am for now. Thanks for the help. Any other advice is still welcome.
Sorry, but it seems to me the only possible explanation is that you do not have a 2600+.
A couple of last things...always disable Spread Spectrum. And if you go to "Frequency/Voltage Control", then high-lite "CPU Vcore (V)" & press ENTER, there are NO voltage options higher than 1.60v?
Just to add, the 1700+ runs at 1.60v, the 2600+ runs at 1.65v. Possibly another clue that you have a counterfeit CPU?
And when under the freq/volt control 1.60v is the highest value that is an option.
I don't really think that the cpu voltage ability is what you determine if this is a counterfeit or not. The last chip I ran had the same options.
I think it is a bios fault. I'm not positive that the bios is the correct version. But like I said before, wouldn't the most up-to-date version of the bios include previous bios update information?
The 5.6 update for my board mentioned support for the 2400+ and 2600+ cpu's... but I updated to the 5.7 version.
I still do not believe that the cpu is a counterfeit.... But something is still amiss.
A new BIOS will contain all the fixes included in prior versions, so if you're sure you have v5.7 installed, any fixes that were developed for v5.6 are included.
What's happening simply doesn't make sense though. The CPU multi is defaulting to 11x & no other AXP Tbred CPU has an 11x multi except the 1700+.
Are you experienced at updating BIOS versions? Did you perform the flash from DOS using a bootable floppy or bootable CD? or did you do it from Windows? For the heck of it, I would try reflashing using v5.6 & see what happens....
EDIT: Hey, I just realized something after posting the above. The socket A Sempron 2600+ (Tbred core) runs at 11 x 166MHz @ 1.60v. I didn't think the Semprons were unlocked, but maybe you got lucky? Check the chart in this article:
Did you look closely at the model number on the CPU? was it SDA2600DUT3D (2600+ Sempron) or AXDA2600DKV3C (2600+ Athlon XP)? None of the BIOS versions for your board officially support the Sempron series so a 2600+ Sempron @ 1833MHz would end up being recognized as a 2200+ Athlon XP.
I had to disable all drives except the a:\ drive. Boot from a win98 floppy, copy the flash file to the RAM (which was under the drive letter D:\ because there was no HDD). Then also copy a file that I have no idea what it was (i'm assuming an exe that coincides with the flash) and then run.
After it completed it said that it was flashed (or updated... don't know the difference) successfully.
I am almost 100+ positive that the part# on the cpu is the axda2600dkv3c. But i will check it again tomorrow. I just don't feel like taking my case apart and fighting the heatsink right now.
Here's how I would have gone about flashing the BIOS:
- download the 6380ev57.exe file from the MSI website & double click on it. From the 6380ev57 folder, copy the flash utility (amifl827.EXE) & the BIOS file (a6380vms.570) onto a formatted floppy.
- make sure the floppy is the 1st device in the boot order.
- boot the system using a Win98 boot floppy & select "without CD-ROM support". When it stops at the A:\> prompt, remove the boot floppy & insert the BIOS floppy.
- at the A:\> prompt, type "amifl827 a6380vms.570" (without the quotes), then hit the ENTER key...it would look like this:
A:\>amifl827 a6380vms.570
Once you hit the ENTER key, just follow the onscreen instructions.
