Windows 7: Detecting incorrect Ram amounts

I don't think you would see much performance lost at all by going to 6 gigs. I doubt you ever use that much even with gaming and Photoshop.

By going to the 6 gig should I expect more stability?? From what I can gather from reading these issues are prone to exisit when exceeding the 6 gig amount and prone to issue with the x58 chipset..................if i go the 6 gig route should I set everything in the bios for the memory back to auto or keep the current settings or something different.............

Thats something smarteyeball would have to answer. All I can say is, you have to be running several extremely complex programs to need more than 6GB.

Ok thanks for that hopefully he will read this and give me his input..................

Sorry for the delay.

Unfortunately, even 6Gb configs suffer this problem. However, more than 6Gb can exacerbate the issue.

For example, I had a similar issue where my BIOS would only detect 4Gb out of 6GB when I initially built this rig.

In my case it was a combination of CPU cooler tension and timings. I now get a 100% detection, but can replicate it with too aggressive timings etc.

***

Firstly, did you manage to do a memtest run with the full 10GB?

Or even any memtest runs?

Without eliminating dud modules/dimms, we could be fighting an uphill battle.


There's also no need to surrender the full 12GB completely, but for the time being I'd put it on the back burner and concentrate on getting a consistent 6GB @ 1600mhz detection.

If that can be achieved, you can add the extra 6GB later.

So the next step would be to run the 6GB kit only in tri-channel @ 1333mhz, same voltages (1.64v/1.35v) with the same slow QPI link etc.

Also, with the DRAM Frequency, 1st information, change the tRFC to 88 (to further loosen the timing)

If it's still failing to detect on a cold boot, you're going have to start looking at other things like adjusting the tension (screws) on your cooler block. Or even removing the cooler and re-seating the CPU etc.

If the screws are too tight, too loose or unevenly tensioned, this can cause uneven CPU pad/pin contact which is one known issue.

I'm not sure whether that cooler has a plastic/metal backplate. Uninsulated Metal on metal has also been known to cause 'shorts' which can affect detection.




Alternatively, is the machine still under warranty?

Yes this is a brand new computer from CyberPower...........not 30 days old yet at deleivery i was having all kinds of BSOD issues which the guys helped me figure out that I had a bad ram stick thus why I am running the 10 gig instead of 12 for the time being.................new ram arrived but was not matching not even the same brand..........I called CyberPower at them them know I was not at all happy with that..........after some discussion with them on Friday they are now sending a new motherboard and 12 gig of ram.............so I am waiting now for that to arrive.......I think at this point with all the issues and this being new its time to replace the motherboard and the ram as well.......going through all this has made me think I should have just gone with 6 gig instead of the 12

Also, yes i ran memtest overnight with the 10 gig in the machine it tests fine............

Curious that it did not detect any errors - that tends to suggest that the board and RAM are probably okay

But hopefully whatever 'gremlin' that is the cause gets wiped out during the mobo/RAM swap.


I assume that since CyberPower are sending you the mobo/RAM - you are doing the swap yourself?

(I don't know if you've built a rig yourself, so please ignore if you already know all the following, this is for just in case you haven't)

Before rebuilding:

► Inspect the new mobos socket for any bent pins prior to CPU insulation

► Inspect the pads of the CPU for uneven contact spots (too see if the current cooler placement was uneven)

► *Optional* Assemble the board outside the case on a non-conductive surface ie wooden or glass table, Motherboard box etc - not the anti-static bag that the mobo comes in, or any cloth surfaces (eliminates potential shorting issues)

► Ensure that the coolers backplate is insulated (if it has rubber/paper washers etc - use them)

► Clean the existing thermal compound off the cooler block and CPU and re-apply fresh TIM (do not re-use the existing applied stuff)

► Use a 1/3/2/4 tightening method when attaching the cooler. ie Lightly tighten one screw at a time in a diagonal pattern, never over tightening one particular screw. (Top left, bottom right, Top right, Bottom left) When all four screws start to 'bite' - don't over-tighten them.

► When putting the mobo in the case, ensure that the standoffs are used - they can be plastic, brass, or even part of the board (don't screw the mobo straight into the case)

► If CyberPower are doing the rebuild - tell them to DO IT RIGHT


And do not regret going 12GB - there are more people successfully running 12GB than there are with issues. Currently, you've been unlucky - but don't let it dishearten you - you should nail it in the end


If you need any further help when the new mobo/RAM arrives, feel free to PM me.

Best of luck mate.

On cold boot memtest does show errors not once it is warm i think I failed to mention that, however, after detecting all 10 gig and running memtest with the computer warm it does not indicate any errors even running it for 6 to 7 passes that part seems somewhat strange to me, do you thunk that still indicates a memeory issue or voltage and timing due to it being isolated to cold boot only?

Also thanks for the advice on the motherboard and ram replacement

If I ran CPU-Z and posted a copy to you would that help you to look at what is going on?
