It actually wouldnt boot at 2133mhz on 1.5, had to be on 1.64 or no boot.

Nice, congrats. No explosion, thats dissapointing.

If you run them at 1600, I'm sure it should run fine at 1.5v instead of 1.65v.

Hi,
I have a Sapphire HD6990. When I choose overclocking bios (Bios 1) so freeze my computer or I get blue screen.
This happens when I start a game or when I start firefox.
HD6990 works well with (bios 1) if I pull down the voltages to the same as (bios 2) (1125mV) but not with the original volt (1175 mV) in the (bios 1).
What's wrong?

Late night. Finally getting my second waterblock installed. Hopefully will be up and running fully on water shortly. I feel like I've been installing waterblocks now for a month. One last run on the P55 mobo.

1.64 volts is fine on 1155. I run 2154 mhz Patriot (sector 5) @ 1.64 all day. Just be sure to tone down your QTT voltage (especially if running an XMP profile, as I am).

What blocks are those? Very nice man. What p55 board are you running (I could check your system specs, & in process kill this opportunity for discussion) & processor? I just sold my P55A-UD7 & i7-875k, which served me quite well across a variety of 5800 generation AMD cards.

When you've got it well installed, throw up some more pictures. I was going to install my second Koolance block this weekend but got tied up in work. I'm curious to your temperatures too.

Thats fine if you feel that way, But when intel say anything over 1.58v can kill the memory controller in the CPU that's something I want 1155 users to know cool.gif

It's not a feeling, sentiment, general inclination, and so forth. My Gigabyte documentation stipulates a safe voltage range up to and including 1.64 volts; wherein, even in the bios, exceeding such illicits a specific warning.

Beside that, my experience has yielded successful when modules in use are extremely high-clock. Problems have been oft occuring when XMP profiles are implemented pushing ancillary voltages far beyond the 1155 limitation.

The fact is, memory designed for a specific voltage in accomplishing very high speed won't operate at the "recommended" 1.5v. I'm informing that, and as it's been fairly well documented besides personal, anecdotal & first-hand knowledge to the subject, the ceiling is flexible at least to 1.65v.

What's wrong?

Try using Afterburner to tweak voltages on the OC bios up. Perhaps there's not enough juice to endure heavier tasks. I've heard varying reports of folks encountering faulty bios flashes somewhere up the chain in the manufacturing process. Try flashing a new performance bios, overwriting the faulty one. What is the blue screen message, buddy?

When you've got it well installed, throw up some more pictures. I was going to install my second Koolance block this weekend but got tied up in work. I'm curious to your temperatures too.

Those are EK Nickel-Plexi waterblocks. I just installed them with the EK Parallel SLI bridge. I had one installed already, but was adding another block to my other 6990, so I had to take both out to add the F bridge connectors. Under Furmark, I saw one card hit 60C while the other was 54C-56C. The card reading higher C temps has Ceramique, while the other one I just completed has Shin Etsu X23-7783D, so I figure I will be changing the TIM on that higher reading card.

I'm currently running an Asus P7P55D-E Pro mobo. I was actually looking for a Gigabyte GA-P55-UD7 mobo forever, but gave up, so I got a GA-X58A-UD7 instead with a I7 960. I have the EK chipset block for the UD7 also. I will be building that system this week and moving the 6990s over to the X58 soon. I already got the I7 960 running 4.0Ghz on stock cooler. Not gonna try to get it any higher until I strap the EK HF Supreme waterblock on it later this week.
