3.99G usuable out of 6G?

Interesting. As soon as I raise the bus clock, it will show the above "usable" memory.

That picture is a blur and This smells of bad ram. I had a set of ocz do this to me. Got some corsair dominator and it never did it again.

Did you click on the picture? I use click-able thumbnails for faster page loading.

EDIT:

as soon as I run the bus clock back at stock, it goes away

 

[OILFIELDTRASH]

Did you run memtest?

 

[BTRY B 529th FA BN]

not while it is clocked like this... let me try

memory hole lulz
check bios settings.

 

[BTRY B 529th FA BN]

I've looked for it in bios but couldn't find a description closely matching it...

It ONLY happens when I run the bus clock up for overclocking. I did a reboot after reboot session to see what setting did it and it only happens when I overclock.... I'm new to i7 clocking and how changing the bus relates to everything else. All i know right now is that ramping up the bus will create that "usuable" memory statement. When I run it back at 133 it goes away.

Not a memory hole nor is bad ram in most cases. Welcome to the mystery of X58. Every board I've used does this from time to time. There is no official explanation that is solid as concrete but before pointing fingers at your board and ram you can try several things...

There's lots of threads galore on this issue over at evga.com/forums.
What memory do you have? My Dominator GTs seem to be the worst offenders of this issue! Go figure! The standard Dominators have NO problems nor do the yucky Crucial Ballistix Tracers - all running 6X2GB at tightest timings possible.

Sometimes you need to remove your heatsink and cpu and re-mount everything. Make sure the pins in the socket are PERFECT and there is no FOD (that would be anything in there that does NOT belong!) present AND make sure the pads on the CPU are SPARKLING clean! Treat the bottom of ANY LGA CPU as you would a halogen lamp capsule. NEVER touch them with your fingers and if you do make sure to clean it up with a swab soaked with isopropanol or similar.

Anyone wanna buy an EVGA 760 Mother board?

 

[Rubycon]

Yes perhaps you should buy a Dell instead!

Seriously sometimes you need to sit down and just play with the settings. You have to be patient. There's lots of information over at the evga forums too. I don't have the 760 which is essentially the same as the 759 that I do have - minus the NF200 chip. The 760 is actually more desirable for those not interesting in going SLI and (in theory) should run a wee bit cooler.

You should probably get another set of RAM to check with as well. What kit are you using now?

Post your BIOS settings using a BIOS template if you could.
If your UNCORE is too high (must be 2X of DDR speed) you will run into these problems quickly. You can jack up VTT but you really should be breaking out the multimeter and metering those pads on the board edge to verify your REAL voltages before using HIGH values in BIOS > +250mV VTT etc.

 

[BTRY B 529th FA BN]

Setting my voltage for my DIMMS at 1.550 results at 1.60v in OS via app reading....

I think I really want to get rid of the board first.. it'd save me alot of headache: just got BF BC2 installed too :\

 

[Rubycon]

Set it to 1.64 in BIOS.

 

[BTRY B 529th FA BN]

Naw, I'm done fooling with this tragedy. I cannot even get the board to stay at 1333 speed (JEDEC spec) It somehow reverts back to 530..

EDIT:

 

[MJinZ]

I never resolved this on my 760, but it only happens on cold boots. I basically have to boot, shut down, and reboot.

Cold means the computer has been shut down for around 12 hours or so.

I have Dominator GT 1600 C7s though. I run it at 1600 C7 without a problem.

That's the ones I have problems with. Not just on EVGA Classified boards either! I truly believe these modules have serious compatibility issues!

Sometimes if the system has been off for a while I'll see 10GB out of 12, sometimes 8. Usually pulling the power for 1 min and restarting fixes it - similarly to what you describe. This also happens on the Asus P6T7 as well!

OP: What BIOS are you running? 64 is the latest (non beta) with 70 being so called Beta. I'm running 70 and still lose 2 or 4GB from time to time.

 

[BTRY B 529th FA BN]

64 on a 64 bit OS

Need a BIOS template to continue further.

I never need to wait. I can literally power on, go to BIOS, see 4gb, shut down immediately and restart, and it's fine.

I think one of the modules may just be weak or something.

Um, the BIOS is accurate. If you set it 1.55, you get 1.55 with some fluctuation.

EVGA E-LEET is not accurate. At all.

BIOS and actual readings on pads is off particularly with VTT and VCORE on my board. Fortunately (the BIOS) readings are actually HIGHER than REAL values.

More of the same with different motherboards -

OK so my template has been plugged in with my actual settings. Have a look Ruby

EDIT:!!!!! with those settings I am getting a full 6Gb reading!!! WOO HOOO! This is only my first boot, we'll see how it acts later.
