Just dropped in the A64 3400..2.76 so far

[WA2]

Not to bad. I was at 2.5 with my 3200 (all stock settings) I never tried to raise anything to really see what it could do. With this 3400 I am at 2.9 on vdimm, 1.9 on chipset, and 1.7 on core. Mem is running 1:1. I have been playing Thief 3 for an hour or so this morning with no worries. I have not tried any higher, yet....

NOW, the reason for the thread....I still dont know jack about these new boards. What settings should I be tweaking to get higher? Just stick with bumping voltage, or are there other little deals to look at? (besides like mem time and the obvious)

Temp is a cool -35c

I think you're just about perfect where you are. 11x250 with the CPU/11 divider is just about right. You could try dropping down to 10x maybe, but I don't know how far your Corsair can go. 2.7-2.8 is about typical for good A64's on phase-change. If you have a CG, then you should disable the 2t timing if possible.

2.76 is an awesome speed man, lets see some benches

it never hurts to go higher though

 

[K4mui]

With this 3400 I am at 1.9 on vdimm and chipset, and 1.7 on core.

Eh, you can hardly let corsairs run at 1.9V, can you?
You mean 2.9V? Would still be impressive...
Disable the 2t- timing is the first thing I'd do on A64 since it's the most important timing at all!

Man wish I had spent that extra $100 and got the 3400 instead of the 3200.

yeah, 2.7ghz+ A64 is insane, I remember candymancan used to be telling me what he would get on his 3000+ is pretty much the highest an A64 will go, but this proves that A64 does have more potential than it seems. NICE OVERCLOCK WA2!!!
someone try 3700+ and see if you can break 3ghz
I didn't see your mach 2, so temp/voltage do have impact on overclocking capabilities eh? Though it seems A64 has less correlation between those two factors.

BTW, what is your chip??? Newcastle or Clawhammer??? If Newcastle, AR or AX???

And the extra $700 for the Prommy.

wow that is a nice overclock. Can you go higher fsb. are these boards allowing one to change the multiplier too? I would start with max multiplier then step back and go major fsb if you can.

 

[oc_byagi]

any Athlon 64 (except for FX), you can change multiplier only lower than the default settins. That's why it is actually worth gettin expensive chips so you don't get limited by the limit of HTT on the system. Plus, A64 isn't as bandwidth hungry, so it doesn't really need super high HTT, just raising the clockspeed will boost the performance big time.

I meant 2.9 my bad. Multipliers are locked. I was thinking about flashing the bios to allow for lower multipliers, but I am not sure it will matter much. I have been reading much today and it seems this is about what they top out at. I have also read that the betas tend to mess peoples **** up often, too. Not sure what to do. Just enjoy it for a bit I guess.

 

[Gautam]

How far you do reckon the memory will go? The proc I'd expect you've maxed out by now. But if your mem can do 276, dropping the multi to 10x would be worth it.

Exemplary A64 systems: setups, results and experiences

Any suggestion, pls let me know.

It was suggested in another thread that I put LDT to 2.5 or lower....I cant find anything of the sort in the bios. I can find "HT" & "Hammer FID". I am not sure what either of these do.

 

[NiTrO bOiE]

Look for the "HT Frequency" setting under advanced chipset features.

There's no point in doing this. Before randomly changing settings, understand what they do, and change them only as appropriate. Your HTT is at 250, and your LDT should be at 4. 4x250 gives you the 1000MHz Hypertransport effective rate that your motherboard supports. You probably won't ever need to go below 4. 3 if you begin to push HTT's above 270ish, I should think.

Hammer FID would be the CPU muliplier.

HT would most likely be the LDT multiplier.

Frankly, I think you're in great shape as it is, and unless your memory can go much higher than 250, you're all set. If you think your memory can take 270+, then try dropping the multiplier to 10x, and the LDT to 3x.

 

[WA2]

As to why I have not changed anything.

In order to drop my multiplier I would have to flash the bios. Do you know of a good stable bios for that? I have been reading over at amdmb and it seems nothing is to hot yet.

Thanks for the info

 

[Gautam]

?

What does Hammer FID do? That should definitely be the multiplier.

Sorry, I'm not familiar with the Chaintech. But if you can't find a way to change it in the BIOS, you can always do some playing around in Clockgen and CodeRed's 64 tweaker. Between those two, you should be able to do just about everything, except for changing voltage.

Oh yeah, what revision do you have? CPU-Z shows it in case you didn't take down the stepping code.

In your sig, the board is listed as VNF3-250, is it a ZNF3-250 instead? Just want to make sure.

SH7-CO

The mobo is a VNF3-250 =)

So a CO rev ClawHammer?
