Hi,

I have just done a new build, Evga Nforce 680Sli mobo, Intel Core 2 Duo x6800, 2GB Crucial DDR2 PC2-8000C5 1000MHz Ballistix Dual Channel Kit , EVGA GeForce 8800 GTX 768MB GDDR3, Tagan TG800-U25 800W ATX2.0, however when I power on, after a few second it gives one longish beep of about 2-3 seconds, and nothing else occurs. The blue, green and orange lights are on, the Case and graphics cards fan run.

I am using the 8 pin connector, and the blue slots for Ram.

When I power on, quite a few numbers flash up, at the time of the beep, number 26 momentarily appears, then some more numbers, 6F, 75, and it then settles at 7F.

Exactly the same thing occurs without an HDD connected.

I have also tried a single stick of Ram in the 1st blue slot.

What are the possible issues that could stop it from posting?

Many thanks for your suggestions
 
ive tried it with no keyboard connected, ive also tried the following:-
taking out the battery for 2 mins an poping it back in, ive cleared the CMOS an removing all cards etc........but still no luck. (7f = Check POST error and display them and ask for user intervention) in the manual :S

I think top of my list for POST freezing at that kind of stage would be RAM. Have you tried each Stick individually in slot 0 ??


do a CMOS clear in between each one. If youu do manage to post it flash the latest BIOS from EVGA.com as the shipping BIOS is bugged +++++
 
Have you got a stick of bog-standard non-boy racer ram you could stick in there to get it to post? From there, manually set the timings, voltage etc, F10, power down then swap the ram back?

agree, if your ram is rated say 2.2v, you need cheapish or lower rated ram in order to boot, once in bios set volts 2.2 for ram.

just looked at crucial site, yours is rated 2.2v.

The exact thing happened with me, if you read This thread, you will see what I did, however, I was not able to resolve it.

I ended up RMA'ing the mobo, and getting an Asus P5WDG2 WS Pro, and the Ram, CPU, graphics card, that I had been using with the EVGA 680i worked perfectly with the Asus mobo, infact it fired up without any problems first time.

I am not saying that your mobo is necessarily the cause, I am just relating my experience with the EVGA 680i. :)

Why'd you go with the P5WDG2 WS Pro over the P5W64 WS Pro?

:confused:

1) I didn't need the 4 x PCI-E x 16 slots of the P5W64 WS Pro.

2) I liked the idea of the 2 x PCI-X and 2 x PCI 2.2 slots on the P5WDG2 WS Pro, in the long term would be very useful.

3) From what I read the P5WDG2 WS Pro O/Ced better than the P5W64 WS Pro, and was reviewed as a fine motherboard, money was not an issue. :)

2) What uses could these be?

3) Where did you read these things? Also money wouldn't be an issue - they cost the same :)

Sorry to quiz just i'm stuck between these 2

So was I, but for the reasons I gave above, I went for the P5WDG2 WS Pro, I would think that you probably will see things differently.

But I am very happy with the P5WDG2 WS Pro. :)

These are genuine questions as i'm unsure on these blanks i have

Can you shine any light on them?
 
Winston:

I would not use all 4 x PCI-E x 16 slots of the P5W64 WS Pro, I would have more use for 2 x PCI-X (on the P5WDG2 WS Pro), which are backward compatable with PCI (if I have read correctly), which would give me a possible use of installing up to 4 x PCI cards.

I read on XtremeSystems Forums, that the P5WDG2 WS Pro O/Ced better than the P5W64 WS Pro.

they cost the same

Not quite, there is approx £12 difference, the P5WDG2 WS Pro being more expensive, but I suppose at this amount of money, what's £12? :)
