Trying to get 2.7 on my 3700 San diego

[s29feb]

When I have had it fial just before windows boots it has always been the ram, run another divider, relax the timming or give it some juice

Looks like the chip won't hit it then...

Try getting 2.5GHz using as follows:

- Multiplier ~ x10
- HTT ~ 250MHz
- CPU voltage ~ 1.525v
- RAM divider ~ DDR333
- RAM voltage ~ 2.8v
- LDT Multiplier - 800 (x4)

ok night shadow i will give it a go. "what does run another divider mean" jsut to make sure...Im still learning, and getting there

"what does run another divider mean" jsut to make sure..

he means dropping down to the 266 divider which with 247 external clock & 11X CPU multi will be running your RAM at DDR320.
Have you set cmd rate to 2T for your RAM at current settings?

[Merlin4458]

yeh its running 2T. always has been

[NightshadowUK]

Tried 2.5GHz yet man?

[Merlin4458]

did exactly as u said nightshadow, and seems stable, so thats good

[Merlin4458]

nightshadow what would u sugest the next step should be in terms of clocking a bit higher?
Cheers

if you have stability, either push on till you find the max with the current volts, or try to see if you can get the same clocks with reduced volts. I suggested 2xram earlier only as temp, 4xram puts extra stress on the memory controller, so running 2x would have ruled out this holding you back

Awesome - let's go for 2.6GHz (FX55):

- Multiplier ~ x10
- HTT ~ 260MHz
- CPU voltage ~ 1.525v / 1.55v (don't go above 1.55v for a 24/7 overclock)
- RAM divider ~ DDR333
- RAM voltage ~ 2.8v
- LDT Multiplier - 600 (x3)

Set the RAM timings to 'Auto' for the time being, just to make sure it'll run stable at 210-ish MHz - we can tweak them later.

At this point it'd be worth running SP2004's 'Blend' test overnight.

Note: Sorry Max Tractor, you got in before me, didn't mean to seem ignorant.

For a quick indication on stabilty try OCCT and s+m

[NightshadowUK]

Or Super-Pi's '32M' test.

[Merlin4458]

ok awesome brb

[Merlin4458]

that was stable nightshadow. NExt recomendation

[Merlin4458]

the minute i put it to 270 or 280 it wont boot just get power down showing on monitor. This was using the same settings said in nightshadows last post

[scrandman]

Hate to rub it in, but my Opteron 146 cruises at 2800 (280x10) on stock volts (1.4V)

Oh yes, it was cheaper than the 3700 too.
