if you have hardware to spare & test... try fully recapping a mainboard & gpu.

Try setting CPU Interface = Enabled in bios. On my Abit AN7 I remember having instability if it was disabled and base clock was > 166mhz.

Just add voltage to CPU and RAM.

Happens a lot to me with NF2 motherboards + ATi videocards...
Haven't found a fix yet.

Good morning! I've been trying voltage changes. RAM is at 2.7 at the mo and I have climbed incrementally to 1.8 for the CPU. Max temp is 52 degrees midway through running Cinebench R10 and all seems stable enough.. It still restarts at the APS test though.. Any suggestions for maximum voltages I should try?

Alternatively, would lowing the FSB to 166 again, then cranking up the multiplier to 3200+ levels work? I've turned it off and gone to a BBQ so can't test right now 😉

Hmm. I also had the exact same on my Asus A7N8X-X, but also my Matsonic MS8177C with VIA KT600 & 8237 Chipsets. What other chipsets could I try?! I'm kinda all out of disposable income right now having dropped £100+ on the latest motherboard & 3200+. Further purchases for testing may have to wait until next month 🙁

Alas - no spare parts or soldering kit to hand. The latest board i'm using is running Cinebench nice and stable at increased voltage, so VRM and caps are hopefully fine? Nothing swollen or burst on a cap inspection anyway

Tried enabling but seems not to have made any difference i'm afraid. Although this is with me running at 200 x 11. I may drop to 166 and increase multiplier to match as per https://www.cpu-world.com/CPUs/K7/AMD-Athlon% … A3200DKV4D.html

Well that didn't work.. Multiple BIOS resets later and back at square 1

My guess there would be the motherboard can't handle 200Mhz FSB reliably anymore.

what exactly didnt work? changing multiplier or running 3dmark on 13x166?
Fastest diagnosis would come from using oscilloscope on Vcore and AGP Vsupply. That would exclude motherboard and leave CPU as the source of problems.

Possible fixes/causes :
1) Get a fan blowing into nForce north bridge chipset (if it helps, you need better chipset cooler/better airflow over Rialto or AGP power)
Possible cause : AGP power circuits are at the limit.
2) Try changing GPU drivers (possible versions to test : 9.1, 10.2, 11.4, 12.2 [since you have 13.4])
Possible cause : Badly compiled code in newest ATI driver causes test to fail.

Additional options :
1) Increase AGP voltage (may kill bridge on card)
2) Increase NB voltage (may not help or will make this worse)
3) Get a new PSU (I'm assuming PSU just isn't coping well enough with that perticular load because of it's age)

If this fails, I would assume a software glitch which makes this card incompatible with your motherboard (or a bug with DirectX/Driver/3DMark installation). You could always swap card for X1950 Pro 512MB AGP.

Well I changed the bus to 166 and the multiplier to 14, and on a save nothing happened - blank screen. I had to clear the cmos to get back in 🙁 I don't have an oscilloscope or volt meter for testing either, so i'm kinda hoping I can just set stuff and it'll work!

14x166 != 11x200

is your CPU unlocked at all? as in can you go above 11? try 12x166

and would be the case for all 3 in that case! Someone suggested replacing the capacitors - would that set things straight? They all game just fine with the 3200+, it's just this one annoying thing they won't do..

try something like 5x200MHz, at least will tell us if its FSB related

OK - gone in at 12x166 - windows boots just fine, CPU-Z gives it:

Core: 2004.69
Multiplier: x 12
Bus Speed: 167.06
Rated FSB: 334.11

Aaaand trips on the test

On trying 5x200 and saving the bios it reboots to an unresponsive blank screen. On a power cycle it starts saying 'CPU is unworkable or has been changed. Please recheck CPU soft menu' but gives an F1 to continue. I continue in and CPU-Z gives me:

Core: 1202.94
Multiplier: x 12
Bus Speed: 100.25
Rated FSB: 200.49

Sooooo theres that.

went back into the bios and set it to 11x200 a 2200mhz CPU.

Core: 2205.20
Multiplier: x 11
Bus Speed: 200.47
Rated FSB: 400.94

For the record, these are my two 3200+ chips

This is the one i've had for about 20 years

This is the one I got last week

There seem to be some fairly big differences between the two! I currently have the recent one in. I know there is a chip off one corner by someone who didn't pay attention when fitting the cooler - but it makes no difference which I use!

The GPU is fine from what I can tell. No funky caps, now running far cooler since I switched coolers (shameless plug - https://www.youtube.com/watch?v=8ueKUWoBu9I) and has a decent amount of airflow going over the Rialto chip. Also having exactly the same on another AGP HD 3850 that as far as I can tell has not been used! or at least - not much. They both completed the test when using a different Intel setup ad the same 13.4 drivers, so i'm not concerned wit them as a point of failure.
Memtest complete without errors on 3 different kits of PC3200 so pretty sure they're all ok too!
