I've already perused that thread yesterday.............thanks anyway timko ;)

My system just trips back off after a few seconds, can't get the PC to stayed powered up if the Mach II ain't powered up, & cannot get into the BIOS to raise the CPU voltage LOL :D

i know its a pain in the ass but why not take the evap head off and put the stock HSF just to see if it is related to the cold boot bug.
 
SD looking good this far. currently 1 hour in prime at 2.53GHz on 1.37V. Concorde how far could yours go on low voltage like this?gonna prime 1 hour at a time then raise HTT until it fails on this volts before i go up.
also used A64 tweaker to disable DIMMS 0&2, seems to help in all areas of the SD.

Yeah I'd like to do that. The trouble is the way the evap head is mounted I can see that I'm gonna have to take the evap head off & remove the mobo from the tray to get the back plate off, in order to remove the front mounting mechanism to be able to get the retail HSF back on it.

A royal pain.........but will resort to that on my days off this week if need be ;)

ah that sucks big time.nothing worse than having to disassemble the works just to try somthing out.thing is if you do and it works you will prob be even more annoyed.
the 3700SD is looking good.20 mins in to prime95 2605MHz at 1.376V. :D

What cooling are you using
 
Posting for a m8 who is having probs setting up the Sata drivers:

Despite pressing F6 for my Sata drive(Samsung spinpoint, tried in both SATA slot one and three) WinXP loading sequence, I was not allowed the option to install the drivers from floppy and now left with a complete install of Windows without SATA drivers...

Could someone please advice me on where to go from here ASAP .


Many thanks
 
When I did my install I didn't need to press F6 to install SATA drivers as my HDs were on the nVidia SATA controller (SATA1-4). Not yet got the SI drivers installed yet as no need for them at this time...

If you do press F6 WinXP Setup should prompt install for mass storage controllers once its copied the inital setup files...

Was lucky as the floppy I have is corrupt and 2 systems can't read it - nothing valuable I presume on them?

ps3ud0 :cool:

using watercooling here mate DD RBX,eheim 1250, dual 120mm RAD. couldnt wait more than 40mins on last prime95 clock so now priming for past 5mins at 2655MHz still at 1.376V. thing is aircooled would be fine at these very low voltages.even though the SD creates more heat than the winnies or venice I think even the stock HSF will be fine up to 1.55V or so.

The SATA drivers are installed from the Driver CD , Nvidia Nforce4, or the latest version from this link (http://www.nvidia.com/object/nforce_nf4_winxp2k_6.53)
This platform driver is NEEDED .

The SATA drivers on the Floppy are not needed to install XP.

2.77ghz is where I had to raise the Vcore to 1.425!

Concorde

Edit: 2.86ghz @ 1.50V

quite similar to mine then.currently about 40 mins into prime95 2.82GHz @ 1.44V.
still much better than the 3800 venice that only got here at its max and that required 1.65-1.68V.
are you running the mem 1:1 or on a divider?ive heard if on a divider the CPUs tend to overclock higher and the performance loss to running asynchronously is more than compensated for. i.e. better overall performace not running 1:1.

going to experiment over the next couple of days with various dividers etc to compare to 1:1
 
Concorde Rules said:
nope, 1:1, 260x11, interestingly I have ruffly the same bandwidth as I did at 280x10 :D

The faster overall clock speed compensates for the lower RAM speed and so there will be points where, as you've seen already, where a lower RAM speed but higher multiplier catches up with a higher RAM speed but lower multiplier.

I saw the same thing happen as I slowly OCed my Winchester 3200 with 200Mhz RAM speed all the way upto 310Mhz - dropping the multiplier twice along the way :)

yeah all down to the A64 mem controller.remember with the bartons how clockspeed had nowt to do with bandwidth.

James looking good there son. ;)
