Windows 7: Can see 8gb in BIOS, but only 4 useable

XMP is actually listed under Advanced Frequency Settings.... Page 37 of the owner's manual (PDF)

Can see 8gb in BIOS, but only 4 useable-xmp-settings.jpg

And it's "overclocked" as defined by the old standards, but not necessarily by the RAM's rated settings. Example, my memory is rated to run at 1866 otherwise it's under performing. However by the old standards of 1366 or whatever, it would considered overclocked... even though it isn't from it's manufactured performance ratings. But that's a debate for another time

And the issue is definitely in the BIOS, not Windows as shown in this image where the BIOS is clearly showing only 4 gig of total memory... even though other 4 is listed. Check out the line that reads "Total Memory Size" on the left hand side reading only 4 gig...

It may be that your Ram is simply not compatible with your motherboard. I had a similar experience with an AsRock Z77 motherboard. The GSkill memory (2x4G) was labelled for Z77 but only one stick was recognized. The shop I bought the memory from had a test rig and as a matter of pride did everything to get the memory to work. Swapped it for GSkill memory tested by GSkill on the motherboard (use Ram configurator) and it worked.
I know they don't test everything but I'll only buy memory tested on the motherboard from now.

I couldn't see your motherboard listed by Kingston or GSkill but it is by Corsair.

I agree with Layback Bear & mjf that it is something to do with RAM incompatibility.
For best results all RAM sticks should be from the one maker & in a matched set. From what I can see one of your RAM sticks seems to be different from the other 3.

I noted this several posts way back there.

If that were the case then the OP should be seeing 6 gig instead of 4. Also I'm not a fan of those compatibility listings because they may not be complete or all inclusive. My old X58 gigabyte MB never listed the Corsair RAM sticks I currently use but I've been using them for awhile without issue. Yeah one should definitely check for compatibility but I wouldn't rely on it as the end all be all. And let's not forget the OP is still under an extremely old BIOS, which subsequent BIOS's have updated memory compatibility. See post 13

That said, it wouldn't surprise me if one or more of the modules were bad or mixed, creating a compatibility issue. I did ask the OP back in post 18 to give us the specifics of the RAM so that we may put this guessing game to bed but he's not answered them (yet)...

So yeah, would help to know a little more about those modules and have those questions above answered.
That would help clear up some stuff and we could move on from there.

Lastly... with regards to memtest running 19 passes without failing the RAM, I'm not sure what to think there as I've a suspicion that memtest my have only tested just the two modules the board is seeing. Thoughts??? It's been a while since I've run memtest so...

That said, the OP can help a lot by proving the RAM info requested.

My two cents.

Yeah memtest only showed 4GB being tested as noted before by someone.

Think I was trying to update the BIOS incorrectly, I think I need to put it on a CD and boot from that? Also I would like to back up my current BIOS first.. Could someone recommend a way to do that please?

I have a couple of Gigabyte motherboards myself and prefer to use @BIOS, which is Windows based, usually in the form of an .exe. Some may tell you not to do it through Windows but it is the easiest way to update a BIOS. Just make sure you read and follow the instruction, and DO NOT restart the PC during the BIOS update unless told to do so.

Oh, and you might disable any screen savers or power management until the BIOS is updated. This keeps the PC from going to sleep or the monitor from shutting off.

Some of the warnings may sound intimidating, but doing it by @BIOS is very simple and quick. You'll need to download the latest BIOS from here first before proceeding to use @BIOS

Let us know.
Thanks nolube - the set bios to defaults made no change - darn.

sygnus21 has some good information on updating your BIOS. Follow the instructions in the post from him (quoted in this reply)

Your board is dual channel capable.

Try pulling slots 2 & 4 (per the manual if only 2 sticks, use slots 1 & 3). Check to see if the slots are enabled in BIOS (same screen in post#1)

Regardless of enabled status, place a third stick in slot 2. Use the same model stick, not the one Gary highlighted in this image

If it is a incompatible issue with that odd stick, you should see 6 GB. Check BIOS again and report the enabled status.

Thanks Gary. That definitely says the board isn't reading the other tow modules. That said, I would add to Slartybart's suggestion to just run two modules and swap them around to see if the other two are being recognized by the board.

Other than that, until the OP answers the questions about the RAM all were doing it flooding the thread with stuff that may or may not be applicable

@ Slartybart... the OP is already using a 64-bit OS. In fact his OS is listed as Win 7 Ultimate, 64-bit. See his first post.

Guys please go through the thread before posting as most of this info is already posted.

Thanks.

Yes, sorry about that. I misread post #26 Also, should that 32-bit be changed to 64-bit because

I deleted post# 38 (Windows bit wise) so it doesn't confuse anyone later.

Yeah post 26 threw me for a minute too but I'm thinking he downloaded the 32-bit installer to update his BIOS when he should have been using the 64-bit one instead. At least I think that's what he meant
