Athlon 64 FX-51 Vcore

cromozone · 12-24-2003, 03:14 PM

I know this is pretty dense of me, but what the hell is the default vcore on this cpu??? I've got one, but the Asus SK8V just sets random things and I want to make sure that I'm giving it enough juice when overclocking. I think it's somewhere around 1.5v??

Sierra_abx · 12-24-2003, 04:45 PM

Default voltage is 1.5v

cromozone · 12-24-2003, 05:01 PM

Aha! A fellow SK8V user

Which bios are you using? How are you finding the board??? Have you tried overclocking via FSB?? (sorry for all the questions, but I'm having lots of fun with this system, infact, I just killed Windows on it!!)

Unfortunately, my board is still not operational. The reseller sent me the wrong heatsink. Was hoping to assemble everything today.

The reseller is about two hours from my home, so I may drive there on Friday and pick up the right HSF. This is the second screw-up. Earlier, my motherboard, CPU and RAM got delayed because another reseller had ordered the wrong memory modules. At this rate, I may get my system operational by 2005.

Damn, that's a shame, keep me updated when you get the thing going. Not many people have this setup. I got a Zalman CNPS7000Cu and 'made' it work with the board. It screws directly to the board, but needs spacers inserted, and the ones supplied for use with Socket 754 are too big. I used motherboard tray mounts instead, worked perfectly

My OCZ ram isn't performing well though, which really shouldn't be the case as it's identical to the Corsair stuff.

Sierra_abx · 12-24-2003, 05:22 PM

Once I get everything assembled, I'll probably be asking you a lot of questions.

I tried sticking my old Zalman 7000 HSF on, but I don't have any spacers, so the fit wasn't tight. I don't want to take any chances with an expensive CPU. By the way, I'm getting a Thermaltake Venus 12. It has a fan speed controller. I'm told you can crank up the fan til it practically cools the entire case! Maximum air flow is 73 CFM.

Edit: fixed typo

cromozone · 12-24-2003, 08:12 PM

lol, sounds violent! With motherboard standoffs the Zalman fits perfectly, but it's more due to the design of Asus' backplate behind the socket more than anything else (that the Zalman doesn't fit in the first place).

Well, one thing at the moment is certain, don't crank your FSB up to 230MHz like I did, as it corrupted my Windows installation on the 74Gb Raptor

Sierra_abx · 12-24-2003, 09:32 PM

What VCore were you running at 230 FSB? In the Anandtech review, the highest overclock Wesley got was 11x225/12x206 or 2475MHz at 1.625V.

cromozone · 12-24-2003, 09:38 PM

I put the multiplier down to 9.5x to try 230FSB. The SATA didn't enjoy it...

I've got bigger issues though, it would seem that the board isn't much liking my OCZ ram. No memory errors when only one stick is installed (either of them), but in a pair, it needs 2.7v for DDR400, and I can only increase to about DDR408 before they flake out. And all this at slower than rated timings. Have PM'd bigtoe about it, but it may just be the beta bios being evil.... Maybe I should try the 1001 Final again.

Sierra_abx · 12-24-2003, 09:49 PM

Interesting. I read that the earlier Bios releases had a more limited voltage range. But obviously, stability should be your number one concern.

Sharkims · 12-24-2003, 10:02 PM

I had the FX-51 and SK8N. When I mounted my Zalman cooler I just used the screws from the HSF mount on the ASUS board to attach the heatsink to the underside plate. Worked like a charm.

I got rid of my FX-51 after waiting and waiting for the SK8V to be available in the US.

Hmmm, maybe I should try that. The only problem is, I want to use the new heatsink I had ordered. I could get my board operational now. But I would be changing heatsinks again when I finally get the right Thermaltake HSF.

Yeah I realised that after I installed it the way I did

Looks like the old final bios on the SK8V is worse for my ram than the new beta.... it won't even boot Windows at 210MHz FSB.

That's too bad. I take it you've already Memtested the sticks to make sure they're okay. By the way, which beta version were you using?

cromozone · 12-24-2003, 10:19 PM

The sticks are ok singly, even at 215MHz, but when both are installed all hell breaks loose. Flashed back to 1002.019 (I believe this is the newest, and it seems to be the highest performing!) and will leave it memtesting over night at absolute defaults (2.7v DDR, both dimms installed). I hope bigtoe can shed some light on this for me, but I don't know if he has played with the required hardware...
