HELP!!!! GA-P55A-UD3 & GSkill F3-10666CL9D-8GBRL (Ripjaws) wont pass Memtester

[Aussie Allan]

  Back to your original post.....some times a small increase in Memory voltage ....say 1.5 to 1.6V can produce more stability....just a suggestion.

yeah ive gone back to default spec settings eg 1.5 volts etc

everyone says to change the uncore multipler etc but this feature is disabled and the only way i can change it is by increase the cpu blck frequency and over clocking my cpu which i do not want to do.

does anyone know of a way to fix that, it seems that its locked to the CPU the i5 750 seems locked.

I REALLY REALLY NEED A SOLUTION, ANYONE ?

[Aussie Allan]

  My fault, not clear enough for one of my fellow countrymen INCREASE Mem voltage to 1.6V and retest or have already done this???

 Aussie Allan living in the fridge

no you were clear - ive already tested at 1.6v 

no improvements what so ever at 1.6

what is strange though is each stick tests fine with out issue at 1.5v

[Aussie Allan]

 While your waiting For support to reply, Another shot in the dark, ...at the main bios screen....hit Ctrl+F1....screen will/should flicker for a millisec ,.... this should/will unlock any advanced features hidden in bios......good luck and hunting .

That worked to bring up more options but none useful for me to change uncore etc or anything for my ram   i wonder if gigabyte can just refund me or change to the latest model i7 board and ill buy a new processor that is as good as an i5 750 with an 8mb cache

I can tell you now that the answer will be to use other memory. I would advise trying Corsair Dominators or Vengeance. There is also Crucial who do some nice  compatible memory sticks.

[Aussie Allan]

 If DM says your mem is not compatible, there a 99.4% chance he's right....can you beg, borrow or steal some other memory to check, preferably some he recommends???...as far as getting another board.........

 You can only ask!....Gigabyte RMA services is probable the best of all Motherboard manufactures ... I have the i7-950 on a GA-X58A-UD3R ver 2 and I can state this is the best board I have ever owned as long as you forget about the two Marvell ports for any advanced performance.....they work, just not at the 6gig speeds as advertised, but with 10 SATA ports to play with, you have to have deep pockets to fill them all.

 ICH10R are better performers and you have 6 to play with, more stable, with about 10yrs to mature to there present state, the only way you can beat them is with a dedicated raid card.......My latest toy/addition is an OCZ RevoDrive x2........100Gb PCI-E card as my boot/C:drive.........gives me 600 MB/S write and 800 MB/S read...........leaves the 6x Raid0 discs I had in it's dust.........have fun.

Can I ask a question???

In your OP you say in use the system after 1 hour of stress (?) running a game it is well & stable......................but you have found under MemTest errors creep in ~ yes?

Now thought MemTest indicates errors is this significant because as you say all is OK when running ~ what put you on the trail of testing the RAM?

Now I use G-Skill in my UD4 version of this board (see a couple of posts I have had issues with some of the info may or may not be relevent to your concerns).

The reason I ask the question is that my other prime interest is photography and the number of "problems" arising in that field that get folk asking will my lens & body be OK how should I test it once I have to make sure it just right.................the direct correlation is ~ if the lens in use seems soft do a focus chart test........if the images are not sharp.....what about post processing in the PC.  In other words do not assume immediately that a problems exists and then try to prove it does and in the case of post processing ~ it is not one size fits i.e. BIOS defaults need some help to be just "so".

I hope you get it sorted to your satisfaction

Yeah they were no better and i informed GB about this when i emailed them - see below:

Please note I have also used the below kits and they have all failed testing on this board (i have tested all sticks in the same way with all settings set to auto apart from the CMZ8GX3M2A1600C9 set where i only enabled Intel XMP memory profile (profile 1):
2x Corsair DDR3 2GB PC-10600/1333 Value Select Ram (VS2GB1333D3)
Corsair DDR3 4GB PC-10600/1333 (2x XMS3 2GB) TW3X4G1333C9A
Corsair DDR3 8GB Dual Channel DDR3 (2x 4GB) CMZ8GX3M2A1600C9
Gskill F3-12800CL9D-4GBNQ (2x2GB kit) as per your test memory list.
Kingston KHX1600C9D3K2/4G (2x2GB kit) as per your test memory list.(WORST OF THE LOT)

yeah error creap in no matter what in memtester and the only reason i came to know about these errors was when upgrading my ram from 4gb to 8gb. if it was for upgrading i would have never known

  Morning guys........Well your now talking to a fellow Australian, a fellow high end PC user , and fellow photographer that thrashes his PC till it squeaks, pops and begs for mercy with imaging software!..........Yes Stability can be subjective for the end user and at the end of the day.......it's your choice!

 What I believe and I'm sure DM the moderator and many other on this forum is....... stable is a black and white subject for good reason, If your system is "Stable" you'll never have to worry about an occasional BSOD, a freeze once a month doing heavy demand runs and the peice of mind that no matter what you throw at it .....it will perform as advertised........a system that seems to be "pretty" stable is good enough for surfing 24/7, running most games at moderate settings and will happily do this until you hit the run button and try pushing your PC with some new game or app

  Do you really want or need this limitation?

 Memtest86 (or 64) was designed for stress testing Memory.....if it shows you have a problem.....you DO have a problem!

 Errors don't mean the memory's crook every-time!  ... It just means that the memory could be crook, or the memory,motherboard combination or it could be the setting that the motherboard BIOS applies even to run Memtest.......If memtest shows errors.....there's a problem that needs to be fixed somewhere!

 Two years ago my wife's work laptop had a "small" problem which she ignored, it steadily got worse over a six month period to the point it finally crashed and could not be recovered, she also lost half her data.

 If you still have them, retest (ONE AT A TIME) but forget about XMP just use auto settings to begin with.....if it fails....input "recommended" settings stipulated by the memory manufacture MANUALLY! in BOIS

 If they still fail......there's a pretty good chance there crook, and an outside chance there not compatible with the motherboard  ....Hope this helps.

Sensible words there. Stability is fairly much a subjective matter and what one person regards as stable another will not.

Memtest isn't infallible but nearly so. If it shows up errors then you can be fairly confident that they are real and it is no point tryiong to ignore them. On the other hand we have the people who will insist on running memtest but only of a cusory nature and then won't hear that there could be problems with their RAM still.

xmp isnt an option as the memory ive got doesnt support that so its not an option luckily lol

After much testing and config in the bios to manual settings etc i have given up all the sticks pass on their own without issue but i think its the motherboard and have read over the net that many people have the same issue. At this stage ive given up and now going to have to purchase new equipment to get around the issue. hoping i can sell what ive got for half i paid for it.

whats really annoying though is gigabyte have not repsonded despite numerous emails, tech support posts or anything they have had 2 weeks and i have sent numerous msg this week and nothing - other companies i expect this but GIGABYTE i do not

will keep you all posted and if any other solutions come to mind please let me know before i sell the system

thanks again everyone

 Well at least you know it's not the memory....Touch down!..........frustrating but your getting somewhere  ...Any thought DM, Absic ?

FWIW ~ I have just dug out the package of my G-Skills and I have the very same pack of 2 off 4GB
