Asus P7P55D + Ripjaw DDR3-2000 (F3-16000CL9D)

[gpb500]

I'd just write it off as bad memory until you get your replacement. As far as memtest reporting...not sure. CPU-Z misreports my memory...I wouldn't sweat it. Next time I'm in Memtest, I'll try to remember to look.

Of course the BCLK is 160, not 1600. Here's an article you might skim through if you get bored waiting for your RMA.

The "PC3-10600" CPU-z reading is the motherboard default. The maximum default is DDR3-1333, anything above that must be manually configured which is why the SPD 667Mhz setting is normal, but then 800Mhz is EPP#1. It is an enhanced performance profile once above DDR3-1333.

Many people mistake this or don't understand this and then say we sell "overclocked" memory blah blah. Confusion.

Thank you

Thanks "Tech"...good explanation and I can see how n00bs would get confused.

Bishop, I checked memtest (i'm using 3.2) and it doesn't try to identify the memory...only shows some bandwidth numbers. Looks like I'll have my replacement RAM on Wed...all quicker than I thought thanks to shipping from the east coast and USPS to return it (gotta love priority mail).

Also, a new BIOS is available to address USB issues. Unfortunately, it didn't fix the USB issues i'm personally experiencing.

[bishop]

Many thanks for the clarification.

Good news about the bios update - fixed my iPhone syncing...I suppose in the next few months we'll see lots of bios updates as they fix things...Good luck with your new set! Hope it works out for you. And thank you for your help/advice thus far.

Good deal about the iPhone. I got the replacement memory yesterday and ran memtest86 and also downloaded the 4.00 version (it reports the same as you saw)...and no errors. This morning the "cold boot" test also showed no errors. I ran prime95 for about 10 mins and no problems.

Note the recent bios change also added an option (i think) for cpu voltage being either "manual" of "offset". It seems "manual" overrides the "auto" setting right below it which is confusing...while "offset" keeps it the same as it was prior. I could be wrong on this but with it set to "manual", my cpu voltage was pegged to the 1.25v number (and stable)...while "offset" caused it to fluctuate between 1.05v and 1.32v. Interestingly, I didn't catch this until I noticed the Prime95 was causing my CPU core temps to run about 6c degrees lower (maxing at 55-ish)...but idle temps were a bit higher. Both settings appeared to be stable. I wonder if the GSkill guys have an opinion on this?

More tests this evening...but it all looks good.

For reference, here's a screenshot (not mine) of the old bios screen:

Glad to hear that the replacement is working out for you so far.
I've sent my pair back for RMA but it seems that the retailer is out of stock so I'll be waiting for a new shipment... I'm hoping the new pair will turn out as successful as yours.

On a side note, it seems that Asus has released another new Bios with more USB fixes and improved memory support. Maybe this will help you with your USB problems and maybe help others with their RAM. Maybe G.Skill knows if any of their products compatibility is improved with this bios release?

That sucks...I hate the whole RMA thing. I have a Micro Center here in town and they have some better pricing and price match with NewEgg (I got my i5 cpu for $149 but most other stuff is about the same price). So...I'm able to just go over there and pick up most of what I need. Their selection of DDR3 memory was pitiful...so I did that via NewEgg.

This morning i had four memory errors...upped the voltage on the memory from 1.600 to 1.625 and that fixed them. So since I was running under spec, I'll excuse that one and plus the address range looked to be in the lower 4GB and I'm pretty sure that pair is good.

On a side note, it seems that Asus has released another new Bios with more USB fixes and improved memory support. Maybe this will help you with your USB problems and maybe help others with their RAM. Maybe G.Skill knows if any of their products compatibility is improved with this bios release?

Oh wow...thanks for the heads-up! I never thought they'd do another so quickly.

EDIT: Tried to flash, got a message that ROM image was not compatible with current BIOS...I guess I'll wait.

EDIT2: I see why...you gave me the link for the PRO board, i have the DELUXE board. My link is here.

EDIT3: No love on the USB printer problem. The update did not clear my prior settings...fyi.

[gpb500]

Interesting discovery today...even though I wasn't getting any errors in Memtest+, Prime95 would only run between 1 and 10 minutes before an error. I tried a bunch of different settings (IMC and PLL did nothing so returned to 1.2v and AUTO). The problem seems to be centered around DRAM voltage...I had it at 1.625 and moved it up to 1.65 which caused it to error out in seconds rather than minutes. I backed it down to 1.6v and was able to run for 30 mins stable before I canceled it...no errors. This RAM doesn't seem to like 1.65v at all. This is running an i5 at 18x and 196 BCLK...8GB (4x2GB).

[G.SKILL]

it seems it would be better to run at 1.6v than at 1.65v

What's more bizarre is the replacement pair, while having the same part number, has different timings and voltage specs in the SPD and XMP information than the pair I kept. Any explanation for this? I'm stable at 1.5875v and 1980MHz...but should I continue walking the voltage down?

Well, I'm convinced that there's a huge conflict with G.Skilll memory and the new P55 boards. I talked to my local computer store today and they said in the past few weeks of building PCs, they've had a significant fail rate with G.Skill ram paired with P55 boards. I'm not sure if this is a memory manufacturing problem, a board manufacturing problem, or more likely, a compatibility issue, but I would just like to express concern to thsoe who are thinking of pairing P55 and G.Skill until this issue is resolved. As you can see, there are many people on this forum alone that are experiencing coldboot, blue screen, boot problems and more with P55 and G.Skill. A quick search of this on the internet will find many other people with these issues.

I went out and bought a pair of OCZ 1600 Low Voltage Golds running at 8-8-8-24. Took me 2 minutes to config the bios and I'm running stable so far. You may find this interesting...when I had G.Skill running before the crashes, I had a nasty staticy feedback noise out of my analog mic ports (both front of the case and on the actual board). Since I've replaced the G.Skill with OCZ, that static has been eliminated. A cold boot tomorrow will close my issue of the blue screen occurences.

The point of this post isn't to point a finger at ASUS, G.Skill, or any other company, but just to advise those who are thinking of purchasing P55 in combination with some G.Skill memory that MANY users are having problems. With that being said, I know many have also successfully paired these combinations. Call it luck of the draw, but this is just something to consider in your purchasing decision.

I must say, G.Skill has fantastic support and they do stand by their product. A+ to them. Thank you for that.

[gpb500]

No, it's not just G.Skill, Corsair users are having the problem as well. That's why I originally thought it was a board issue, and replacing the MB didn't change a thing. See here. And more here.

After RMA I'm good...I think.

I think you're right...luck of the draw. XMP data on my two pairs doesn't match and that is a different issue. I wonder if they matched initially before my RMA. Glad to hear you're up and running!

[bishop]

The things we do to enjoy the latest and greatest, eh. Thanks for your help GPB500. I am interested to hear about the XMP data on your two pairs...maybe they made some changes after the intial batches went out.

Yeah...what fun!

Well I'm sure I won't find out and if I do, I'm sure I probably won't care.

there are few people would like to know about these complicated values
even the model names are the same, but we fixed the spec a little
that's why you found the difference

the spec we guarantee is for most cases, but some may reach the spec with lower voltage
it would be great if we could run at lower voltage
