Strange 7970 Problem

[p_monks33]

Ok, I just finished building my new water loop, and it includes
I5 2500k, Asrock Extreme 3 Gen3,7970 XFX BEDD with EK waterblock
I had the CPU under water in the same motherboard with the same 7970, The 7970 was on air before I added the waterblock and it worked flawlessly. I finished up my build and bled the loop. Turn on the system and get a Dr Debug 62 error. I read around on google and try pulling the GPU out of the PCI slot and booting on IGP. It works. I read into it a bit more, and go into the bios and select IGP as primary GPU instead of PCI Express. Put the 7970 back in the slot, and it boots just fine. I cant see the bios at startup, but everything else works. EXCEPT.. Now I have lost the ability to adjust voltage on my 7970 and its got me going nuts. This is why I built the loop, to overclock things. Does anyone have a suggestion to why it is doing this ? Maybe it errors due to no fan being plugged into the GPU?

Still working on it.

First step is to update/re-install the driver and whatever voltage control program you're using.

Im more worried about why it wont post if I select pi-e as primary over the igpu. I will test in another system tonight.

If you haven't already, CMOS battery out, reset mobo BIOS. Load optimised defaults and go from there. I found the Asrock Extreme 3 Gen3 BIOS to be a little tempremental.

I did clear cmos. I will pull the battery.

Anyone else had a problem like this?

 

[p_monks33]

Bios update fixed the main issue. I still for some reason cannot overvolt.

Can you flash it, I mean until you figure it out anyways?

I have my cards flashed to 850/2000, it's not like when you're on water you'd ever run stock again anyways

I'd just flash it to the max voltage you were planning to run before then find your stable clocks and flash those in.


Edit: Also sometimes with fullcover blocks they touch places they shouldn't, you may have missed a washer/rubber or whatever EK is using now which could cause issues with your gpu. I would check the mount//re-mount it.

I dunno what the hell is going on with my computer. I did a full reinstall of windows. When I enable unofficial overclocking in afterburner, I see all zeros for selection in the sliders. I also cant move any of them. Any ideas?
