Vapochill and Winny/Venny Voltages

[K404]

For the few of you here that use Vapochills with Winchesters or Venice procs, what kind of voltages did you use to get your max stable OC`s? With ~1.6V across the core, i`m not even getting 2.8 stable. Does a vapochill reduce the voltage needed for a stable OC, or does it deal better with the heat produced by turning the voltage up enough to hit higher clocks?

Thanks,

Kenny

It tends to be a bit of both, they need less volts and can handle more volts.

For the absolute max OC, 1.8/1.9V is normally needed, 1.7/1.8 tends to get pretty much 24/7 stable speeds without any problems.

However, I have seen quite a few winnies and venices that dont always respond to changes in Vcore over certain values, the amount they respond to Vcore seems to vary from chip to chip.

Hey G, thanks for getting back to me so fast I`ve been...not scared, but wary of trying 1.7+V across the core as i`ve taken on board peoples opinions that voltages above this are bad.

Will try it, not much to lose

Thanks,

Kenny

Update: Nothing. 1.7V (ish) gets me..still not stable at 2.8GHz. Grrrr.

Might be the limit of the chip, my newcastle 3500+ craps out at about 2.7, dont expect miracles from winnies, some of them arent great clockers.

I thought phase was supposed to push back the limits of the chip?

Well heres a dilemma.... sell vapo or replace Winchester with Venice or...X2?

I think it's a good excuse to get a venice LOL.

On the other hand the limit could be the CPU, some winnies do not react to high FSB - typical max FSB is 300HTT, more like 290ish on average. Some Winnies have memory controllers that are simply not stable above 270 HTT/FSB.

Lets not forget, the winchester can still pump out a lot of heat when overclocked so that might be your limit.

Also, try messing around with the other BIOS settings you have at your disposal (chipset voltages etc......)

What PSU are you using??

Hey Mav. Have tried upping all my voltages, both in turn and all at once to try and find a limiting factor. My Winchester will quite happily do 300FSB, but obvioulsy with a lower multi. Temps on the evap say -2x.x degrees even under load, tho my BIOS says the temps are the same as they were on stock air.

PSU is a Tagan 480U-01.

I`m out of ideas, and slightly disappointed. Ah well. I AM happy that I got it working first time, no disasters

I got a 3gig winnie for sale its subzero friendly too I think it was mav's

 

[K404]

*possibly tempted* What rating, how much? What cooling did you use to get to 3GHz? Mind i`m on a lowly stock Vapo PE

Ur new avatar is....creepy.

It was my winnie - it's a beaut 275x11 at 1.65v mach2 cooled r134 gas, in some ways the scores I got from that were more satisfying than with my FX - purely because they were not that far behind, that CPU opitimises VALUE FOR MONEY.

Evap temps don't mean squat man - you need to see CPU temps in the BIOS or in Windows use Speedfan or motherboard monitor so that you can see whats going on.

Using speedfan I noticed that running 1m superpi on my Winchester upped the temps by 15degrees - the evap temp moved by 3 degrees during that temp increase.

300fsb = excellent overclock, and above the average for a winchester CPU - sounds like you need an upgrade - a re-gas on the chiller may help too.

Also make sure you have a good PSU, a 20pin in a 24pin socket (even with adaptor) is not always good for stable overclocking.

That aint good then, coz my speedfan and BIOS (well...speedfan reads the BIOS) read the same kind of temps as I got with my stock air cooler. Idle at ~28 degrees, loaded gets me ~35->50 degs at 2740MHz.

300fsb = excellent overclock, and above the average for a winchester CPU - sounds like you need an upgrade - a re-gas on the chiller may help too.

Mav

I know I got an above average Winchester, thats why I was hoping a vapo was gonna let it go even further. I`ve thought about a re-gas but between the time it takes for the pressure to drop after shut-down with R404(8hr downtime=unhelpful), and the fact that the re-gas cost could be put towards an X2, I dont know if its worth it.

Also make sure you have a good PSU, a 20pin in a 24pin socket (even with adaptor) is not always good for stable overclocking.

Mav

I got Nforce3Ultra, so PSU slot is 20-pin. Got a Tagan with the 20-pin adaptor on it ATM.

Sounds suspect to me, I wonder if the Vapo is working correctly?

Plus the Vapo does suck a lot of juice from the PSU, I am not saying thats the problem but it could be.

Also try using a different version of speedfan just to be sure the readings are right and check for a BIOS update that recalibrates the temp sensor.

X2 CPU is only good for Video, an FX would be more appropriate as it's faster on al other benchies, runs cooler and uses less power - I have one for sale at the moment

Well.... to be honest, A cock-up on my part wouldnt surprise me, given that I`d never even SEEN a vapo in the...metal till a couple weeks ago. Its definately doing something as I can bench at 2740 with lower voltages across the core. Will try checking for BIOS and Speedfan updates.

The Evap head is definately making proper contact with the core. The vapochill thermal compound was used properly, tho possibly a bit too thick on the core.

Thanks for the hints

Kenny

Update: BIOS flash did nothing, still to try Speedfan update or MBM.

2nd Update: Updated speedfan, says the same as it did before, Installed MBM, agrees with BIOS.
