A bit a of a strange one ? (Very) recently upgraded my graphics card to a 5970 (managed to grab one at £524 in stock spur of the moment thing - I couldn't help myself!).

The problem being it fails to boot form cold most times (P6T one long beep followed by 3 shorts beeps - no graphics card). I have to soft reset and it boots fine. Is there a setting that is not allowing enough time/voltage to the 5970 for it to boot from cold ??? I have recently also upgraded my PSU to a nice shiney OCZ gold 1KW modular unit which is perfect (same happens with both my jeantech 700W PSU and OCZ 700W psu so I dont think its the PSU ?)

Anyone elso had cold boot issues with the 5970 ??? :confused:

I was waiting on the GF100 (whatever it will be called !) but the 5970 was calling me ! :) a couple of 8800GTX's soon to be up for grabs as a result.

check psu and motherboard connections that they are firmly in place

even more importantly what rails theyre connecting to? look at your psu manual.. I connected each pci-e socket to a different rail, make sure theyre receiving 20A-40 Amps of current each
i got two of these babies, 4 power connector leads plugged to different sockets on psu, each one with 20 - 40 amps going through it.

Hi, yes I have tried 3 different PSU's and checked several different rails on my OZC 1000W Gold supply, so I dont belive it to be the PSU. I have my PSU connected directly into the mains (no surge protector in line), however I do have a surge protector connected on the same ringmain (but not in series with the PSU), I can't see how this could have an indirect effect on the boot.

System boots fine after a soft reset, just not from cold ?? Is there a setting in the P6T bios that can be altered ???

Edit -
I have removed ALL other electrical items from the same ringmain (study has its own ringmain!) so all thats connected is the PC/VapoLS and the 27" Dell Ultrasharp - SAME problem.
All connections checked on the motherboard etc all seem good - no cold boot/3 beeps, boots fins after reset with power on!

I have returned all settings on the P6T to auto/default settings and so far it seem to be the cause of the problem (I was running the same O/C BIOS settings with the new 5970 as I had with 8800GTX's in SLI).
It seems I'll have to work my OC setting back up again to see where the Graphics problem in the BIOS lies !

Latest BIOS installed?

Yes - although next to no updates between latest and previous P6T BIOS (just new cpu's).

I figure I'll have to have a tinker with BIOS settings and see where the GFX card stops cold booting ! Any ideas on what settings may cause GFX cold boot issues (PCIE voltages etc!).
 
Occasionally i get cold boots on my p6t dlx v2, switch on to be met with a black screen, or sometimes it stalls at the express gate menu, hit reset and it boots fine, system is clocked at 4.0ghz, tested stable with p95, and LinX. I thought this was caused by a dodgy dvi cable i had a while back, replaced the cable but it still happens every few days. Ive had this issue now with 3 different gpus installed, gtx 280, 7300gt and 8800gt. From a bit of searching various forums, some people cured this with a bios update.
 
@Carlos, is there a setting in your bios for "Memory Low Gap" or similar ?
If there is, set it to 2gb or the nearest to 2gb. On auto it should default to 1560, which is not high enough for a card with 2gb of memory.

Hi Kitfit1, had a good look through all the P6T Bios settings and can't find anything that vaguely resembles the "Memory Low Gap" settings.
P6T BIOS version 1004 (from memory the previous bios didn't either).

I think it must either be a cold voltage or timing thing in the BIOS, works ok when not overclocked as stated above, I just cant put my finger on the cause just yet ??

Hi Setter, I have tried several Bios versions with no joy, currently running the latest and its the same. ?? do you have any settings in your Bios (what vers?) like Kitfit1 in the above post has mentioned ??
 
Im on bios ver 0504 that the board shipped with. Have never seen an item like kitfit1 has described.
 
In the DFI UT x58 and in my current Classified, in the memory section there is a setting for "Low Gap".

It's to map the gfx memory, which if not set correctly can result in a no boot or failed boot.
I was under the impression that most x58's had this in the bios somewhere.
