Maximum FSB overclock which can run Windows is 225 - 226 won't even post. Maximum STABLE FSB overclock is 214. These are with the default multiplier of 11, for a maximum speed of 2475MHz, maximum stable speed of 2354Mhz.

Don't know why the FSB can not be raised above this speed, even if I lower the multiplier, I have 500MHz RAM, I should try it again now that I just got around to upgrading the BIOS today. (was using BIOS 1.0 before).

I only use default voltage, overvolting sounds too likely to fry stuff IMO.

Edit: Just confirmed that the 1.2 BIOS is even less stable overclocked than 1.0. Got a crash when raising the bus speed passing 208. Didn't even make it to 214. On the theory that maybe this is just because I was adjusting it on the fly, I tried changing the setting in the BIOS instead of in Windows. Still doesn't post past 225. The auto-recognition of this and change to safe mode is much nicer than the way the old BIOS required me to jumper it to reset all the settings.

Another note: It doesn't like the clockspeed varying on the fly much. Turning on DOT (even the default 3% dynamic overclock setting) makes it too unstable to compile linux stuff even with all other settings default. However if the speed is not varying on the fly it is stable at 2354MHz.


Did you reduce the HHT mutiplier from x5 to x4 instead..?

Tried that too, no luck. From this thread I suspect it might be because I am using all 4 SATA channels. Also wondering about my PSU after the recent memory review -- It's a 350W Antec, but I am reading 11.67V on the 12V rail and 3.14V on the 3.3V rail. This drops to 11.50V and 3.11V when running Folding@Home and direct3D tests to keep the video card busy.

Edit: On a hunch because of these crappy readings and the recent review, I tried raising the memory voltage by 0.05V to 2.70V. This fixed my stability problems in WCIII even when not overclocked so far. I'll have to see how things run when my new 520W PSU gets in.

UPDATE: My OCZ PowerStream 520 came in. Interestingly enough, the motherboard thinks the 3.3V line is undervolted until slightly past the point where the light on the PSU turns red. Since it thought that particular line was undervolted with BOTH PSUs, I tend to think it's a motherboard issue. The new PSU corrects the 12V level though.

Even with the new PSU, the system won't POST at 226MHz bus with otherwise normal settings, or even underclocked CPU. I got it to POST with a 250MHz bus however, by lowering the memory clock multiplier (seting it to 166 in the BIOS instead of 200, however it then locks up trying to detect the RAID array, which agrees with the idea that the first 2 SATA channels are tied to the HT speed.

I agree this definitely needs to be defined..

But hope the review is awesome.

Mine is running at 2500Mhz with the multiplier dropped to 10, FSB at 250 and 1GB Adata DDR500 running 1:1 at 500Mhz 3-4-4-10. Abit AV8, 1.575v. It literally won't do 2510.

Edit: I didn't even realize Anand posted this or I would have mentioned that while the Abit AV8 is by most measures great, it has well documented problems with Antec Power Supplies. A quick visit to Abit's forums confirm that a large number of people (including me) can't get the AV8 to boot with Antec PSUs. It will boot up to about 2550, but anything above 2500 crashes in 3DMark. 10x250 is completely stable, Doom3, prime, whatever for hours on end. I run my system at the specs in my 3DMark Project full time.

Athlon 64 3500+ @10x250 1.575v
Abit AV8 1.1 9/03 BIOS
250 FSB LDT 4X
A-DATA DDR500@500 3.0-4-4-10 2.8v

Cpu Used = 3500+ 90nm socket 939
HSF = Zalman all copper c7000
Memory = 3-3-3-10 (Run at FSB 1:1) Note* Asus calls this setting 2:1 but CPU-Z shows that it is running at same speed as FSB
HTT=5x for all settings (I never lowered it to 800)

Overclocked FSB speed = 220x11
Overclocked CPU speed = 2.4
CPU voltage = 1.5
Motherboard used to overclock = A8V Deluxe v2.0 (bios 1.07)
TEMP = 38 celcius idle / 47 celcius prime 95

Overclocked FSB speed = 227x11
Overclocked CPU speed = 2.5
CPU voltage = 1.525
Motherboard used to overclock = A8V Deluxe v2.0
TEMP = 38 celcius idle / 47 celcius prime 95

Overclocked FSB speed = 236x11
Overclocked CPU speed = 2.6
CPU voltage = 1.6
Motherboard used to overclock = A8V Deluxe v2.0
TEMP = 51 celcius idle / 60 celcius prime 95

Attempting 2.7 later tonight

if someone shows me how to post CPU-Z screens on anandtech I will do so at all settings.

How many people posting on this thread are using a Gigabyte GA-K8NSNXP-939? Anyone using Corsair TwinX1024-3200XL memory modules? Or trying? I haven't had much time to try and overclock my system, seeing as how it's not even stable at 200...

WindowsXP Pro(sp2)
AMD 64 3500
Gigabyte GA-K8NSNXP-939(F5 bios)
Corsair TwinX1024-3200XL 2-2-2-6
(2)WD Raptor 74gb in RAID 0
BFG 6800 Ultra OC
Ultra 500W X-connect PSU
Thermaltake Xaser III

I am. I haven't overclocked yet. I'm waiting on getting my cooling squared away before I attempt anything.

If you're water cooling, you can ring quite a bit of performance out of a 3500+.

Check your timings? Better not be using the SPD setting for your ram and should be using the voltage you ram requires. I was using SPD settings on my ram (DDR 500 Corsair) and was barely able to overclock, also was using too low of a voltage (suppose to be 2.8v)
