Barton 2500 OC issue here

[addiarmadar]

I got the following:

Barton 2500+ (stepping aqxea)
Asus A7N8X Deluxe Rev 2.0
Geil PC 3500 Dual Channel DDR 1gb kit
PNY Gefore Ti4600
Sound Blaster Audigy
Thermaltake 420wt PSU w/ PFC
Segate 80gb SATA 8.5ns seek

With tons of reading the barton 2500 with this stepping should be able to do the 200mhz clock speeds with 2200mhz but my comp has been doin some odd crashes. It will boot into windows ok but either when loading a game or closing a game I'll get the blue screen. During the game it runs great. I couldnt do the benchmark 2001se even in stock setting but the games runs fine at that the stock setting. I believe that this a compatibility issue.

For this CPU, what should my voltage be for 200mhz clock cycle? I just put it at 1.8 volts today but havent tested it yet. Since Im using the slk947u and the tornado 92mm fan, my cpu temp has yet to break 50c. Any other ideas and suggestions would be great. Thanks...

Stay at 1.8V don't go above that, you should be able to get 11x220 out of your setup right away, also increased vdimm to 2.8(or more if your mobo allows it) just stay under 3.0 because that'll void your warrenty on the memory. Run a program called Prime95 for about 24 hours, if your computer doesn't crash, then it's fine, perfectly stable, if it crashes then something's wrong.

Yeah thats my call too. Any higher than 1.8 would probably toast my chip even at 40c temps. Is it really necessarry to jump the vdimm when the ram can do 216. Its at 2.8. Anywho I will try to jump it 2.8. Should I also change the charge delay to 10?

Sorry typo. Im using PC 3500 (216mhz) ram and its at 2.6 volts. This ram should be at 2.8?

My aim is just like my other barton 2500, dirrerent stepping thoug, and that is to get 3200. Id just want 2.2ghz. Ill try that exact config when I get home.

[scottchen]

why not to max allowed by manufacture for the ram? then you might run at 225 at 2-2-2-10. And that's GREAT.

Heh my 2500 does 3200 on 1.6v.

Looks like either I have a bad ram slot or a bad ram chip. I did the memtest86 and it made over 160000+ errors on test 5 and 27 on test 6. All errors were with tests that exceeded 514mb. I need to research this over but any info yalll have on this would be great.

Ok, which brand has that?

[addiarmadar]

Ill be looking into the OCZ Dual Channel kits. However I did found the problem. One of the paired ram was bad. I did the memtest86 on each seperate dimm and one only had 4 errors and the other had 300+ errors. The Dimm in using can pass the benchmark fine now just my score is a bit pitiful (8764), only using a ti4600 on this rig so far.

I'm helping a friend overclock.
I've never tried to overclock a VIA chipset before, so I need a little help myself.

He's not trying for a huge overclock, just looking for 2200MHz.

His system:
Enermax 431W PSU
A7V600 (VIA KT600 chipset)
XP2500+ (AQZEA)
1 Gb Kinston HyperX PC3200 CL 2-2-2-6
AIW Radeon 9700Pro
etc.

CPU Voltage 1.75V
RAM Voltage 2.75V
(Don't know if I should raise these anymore)

It fails Prime95 and randomly crashes at 2200MHz (200x11).
What gets me, is if I run Prime95 with the settings that use almost no memory, it takes MUCH longer to crash or fail than in the blend mode.
Were talking 3 minutes for a fail on blend mode, and 3+ hours before system crash on the other setting (no fail just BSOD).
Even then I'm not sure it's Prime95 that makes it crash.

That doesn't make sense to me though.
The memory isn't overclocked, and the chipset is supposed to support 400MHz FSB.
Yet it seems as if the CPU is fine, or at lest better than the rest of it.

Any comments or suggestions?

Well for the via chipset you gonna have to drop that multiplier to 10 at least and try looser timmings like 2.5-3-3-3-6 or 7. Even if you could get the clock to 200, you would only get 2000mhz. Try the looser timmings first but most likely will have to drop that multiplier anyways. I got a kt600 ultra mobo and dropped the muliplter to 10 but I got 215 out of it, which is 3200 speeds cant complain as long it was stable.

VIA chipsets don't unlock the multipliers, as far as I know.
In any case, it isn't changable in the A7V600.
Did you hardmod yours?
I'm not looking to do any hardmods.

Besides, 200x11 is the exact same settings of and XP3200+, a processor that the board supports.
I've tried the looser timings, but not with the higher voltage.
The looser timings (2.5-3-3-7) failed to post, go figure.
The SPD timings 2-2-2-6 actually post, kinda weird.

I'll try loose again, but don't anticipate any change.

Open to comments and suggestions until I post it as fixed.

Ive been a via user for quite some time now so I have a few tricks for unlocking multipliers.

Anywho, most of the bartons will not do 200 with multiplier at 11, well at least the 2500+. The 3200 stock is 200x10.5 .

The ram maybe good for the 2-2-2-6 timmings but just like I learned recently your mobo will always have the final say as wat timings you will use.

For gigles does your mobo adjust clock speeds by 1mhz at a time? If so try doing 193mhz. Also make sure the agp and pci are no going over 34-35mhz.

I don't have access to the computer right now.
(my friend just left for thanksgiving break)
I'll see him sometime this week, but I'd like to get as much info as possible before then.

What are the highest voltages you'd use?

I've never had to up the cpu voltage beyond 1.7V and I've never had to up the memory voltage at all when overclocking the XP2500+.
I've already pushed a couple of XP2500s up to 200x11.
I've only had to drop the multiplier to go beyond.
Of course they were all on different boards (nVidia chipset).

What are your methods for changing the multiplier.
I think he'd settle for a 200x10.5 or 2.1GHz.
He's just not crazy about hardmods.

I've been using memtester86 to test the memory.
At an FSB of 333MHZ and a 333MHz memory bus I get no errors.
I up the memory bus to 400MHz and I get many errors (Test5).
Frontside bus hasn't changed.

I read that test5 errors weren't necessarily memory problems, but the memory bus is the only thing that I changed.

What are your thoughts on that?

The chipset doesn't allow me to lock the AGP/PCI frequencies.
I'd like to know cooresponding frequencies before attempting incremental adjustments as I don't think his motherboard will show those.
Example: 200 - 66/33 (FSB - AGP/PCI)

BTW, the XP3200+ stock is 200x11 or 2.2GHz.
200x10.5 is only 2.1GHz which is the stock settings for the XP3000+

[Bahumut]

Scratch that, apparently he got the multiplier unlocked.
(I'd still like to know your unlocking methods for future reference)

He actually pushed the processor up to a 200x11 and left the memory at 166MHz and had no errors using memtester86.
He's running prime95 as we speak and doesn't yet have any errors.
Of course he got no gain in performance over the 166MHz FSB.

I'm leaning strongly towards the memory being the problem.
CPU voltage 1.7V.

What's the highest value I should set the memory voltage at?

with heat spreaders 2.8-2.9 should be ok

without heat spreaders i would stop at 2.75 maybe a lowly 2.7.


If it isn't a P6 then it isn't a procesor

[Bahumut]

Thanks, man.

They are Kingston HyperX sticks, so they have alluminum heat spreaders.
I'll keep the voltage no higher than 2.8.

Don't quote me on this but i think kingston covers 2.8v under warantee...so you are fine...
