OCZ3P2000EB2GK issue

[eternal_fantasy]

• OCZ part number:-OCZ3P2000EB2GK

Here is the e-mail sent to RyderOCZ, and thought I should also post it here to get more opinions on my problem.

Hello eryder;

Following my PM to you over at xtremesystems.org, I have spent a day on this pair of 2x 1GB DDR3-2000 kit from OCZ.
http://www.ocztechnology.com/product...dwidth_edition

Tested on both the ASUS Striker II Extreme and the Maximus Extreme platform, the memory kit seems to be faulty.

All tests are done with the VDIMM at the RATED 1.8V, as reported in the BIOS Voltage Monitor.

Initial boot after the kit was installed on the S2E, with the recommended 9-8-8 settings, 1t, and the rest on AUTO, the system booted and went through POST, then under DOS windows reported my installation was corrupted. Reverting back to everything on AUTO my OS is still reported as corrupted. Following a fresh Windows installation, then setting the memories at a more relaxed timing of 1800, 9-8-8 1t, I was able to start windows. However using the command "sfc /scannow" under Windows Vista to check for system file integrity, it found partially corrupted windows system files, and was unable to fix them.

I then move the OCZ kit to my "server" computer with the ASUS Maximus Extreme motherboard, which has been running at 1.8V, 8-7-6-21 1t with 2x 1GB CellShock DDR3-1800 memory kit for over month, stably.
Using the same settings as the cheaper 1800Mhz kit the 2000Mhz OCZ fails to post, causing all sort of issue, such as "corrupted BIOS", "no keyboard connected", "no boot drive found" etc.
Resetted the CMOS, the memory was allowed to AUTO on everything, and booted fine with auto configured settings of 1333Mhz 9-8-8-24 1t. A run of the Windows Vista built in memory diagnostic tool was performed on the memory, and all seems fine.
I then preceeded to raise the memory frequency of this kit in 100Mhz steps, and upon reaching 1700Mhz, errors were found, and once windows was started, a BSOD soon followed.

Note that EVERY memory setting inside the ASUS Maximus Extreme, BIOS version 0904, except the Voltage(at 1.8V) and frequency, was set to AUTO.

What I find puzzling is that not only it does not run at it's rated speed, it does not run at the settings a lesser, cheaper, slower rated DDR3-1800 kit does.

Please can you shed some light on how I should proceed, and weather you like to have more information, or test using different settings.

Test setup: OS: Windows Vista 64x
ASUS Striker II Extreme BIOS 0601
Intel E8400
nVidia 8600 GT
WD RaptorX 150GB

ASUS Maximus Extreme BIOS 0904
Intel QX6850
nVidia 8800 Ultra
4x Samsung 32GB SSD

Another thing I would like to know is I was wondering under what condition/platform/DIMM slots did OCZ test these rams at for it to reach the 2000Mhz 9-8-8?

Thanks for any help!

I have carried on testing the kit using the ASUS Striker 2 Extreme motherboard (as suggested by Ryder), 1.8V vdimm, and have found the following settings that did not return any errors using the Windows vista Memory diagnostic tool;

One stick was able to pass the diagnostic at 2Ghz 9-9-9-(36)-(51) (2T) all else AUTO (bracketed settings were AUTO configured)
The other could not pass the diagnostic at any timings at 2Ghz.

Fail?

[RyderOCZ]

Test at 1.85 - 1.9V, Please.

[eternal_fantasy]

I made the purchase thinking I'm getting great binned DIMMS that ran at 2Ghz with only 1.8V, and would have great overclocking potential...

I really doubt the Info on the website are wrong...

2000MHz 9-9-9-28 1.9V - OCZ3N2000SR2GK - OCZ DDR3 PC3-16000 NVIDIA SLI-Ready Edition

2000MHz 9-9-9-28 1.8V - OCZ3P20002GK - OCZ DDR3 PC3-16000 Platinum Edition
2000MHz 9-8-8-28 1.8V - OCZ3P2000EB2GK - OCZ DDR3 PC3-16000 Platinum Enhanced Bandwidth Edition
2000MHz 8-8-8-28 1.9V - OCZ3FXT20002GK - OCZ DDR3 PC3-16000 Flex II Edition

If the Platinum EB voltage are wrong then you'll need to add 0.1V to the Flex II and both Platinum kits. They seems to share the same IC, or share the same wrong voltage ratings.

Anyway ran the kit using 1.9V, and the following results at 2000Mhz:

Keep in mind that the kit is rated at 2000Mhz, 9-8-8 @ 1.8V


Stick 1:
1.8V 9-9-9
1.9V 9-9-9

1.9V 9-8-8 (ERROR)

Stick 2:
1.8V 11-12-12
1.9V 11-11-11

1.8V 9-8-8 (ERROR)
1.9V 10-10-10 (ERROR)
1.9V 9-9-9 (ERROR)
1.9V 9-8-8 (ERROR)

Seems that one stick is very much worse/faulty then the other. However even if both sticks performed the same as the first stick they would still not run at rated speed and timings. Hence I would like to know under what conditions did "Each module is 100% hand-tested for quality assurance and compatibility", and I would like to duplicate those conditions.

Configuration:
ASUS Striker II Extreme
Intel E8400
nVidia 8600GT
WD RaptorX 150GB
Enermax PRO 82+ 625W

CPU@3Ghz
CPU Multiplier@x9
FSB@333Mhz
Memory Frequency@2000Mhz
Memory Voltage@1.8V-1.9V
All other settings on AUTO

I really wanted this pair of memory to work, I really tried... RMA would only be meaningful if the new pair of memory are actually tested before they are shipped, or it'll just be a waste of time.

I have contacted the retailer, and have arranged a refund of this kit if the issue was not resolved before noon 29th, GMT.

[RyderOCZ]

Why can't the website be wrong? People make a typo, same as the sticker on the ram can be wrong.

Why would we have to add +0.1V to the other 2 kits that are already rated at 1.9v?

You posted these results over the weekend, OCZ guys get some time off too

What test numbers are you getting errors in? Are you testing in Windows or memtest v2.01?

[eternal_fantasy]

Right... so how the hell am I suppose to know what I am paying for if everything "can be wrong"?
Is this even rated at 2Ghz? or is it "can be 2Ghz"? maybe a typo too?

I brought it under the illusion that this kit can run at 2Ghz @ 1.8V.

Oh well, it seems that I've brought the wrong set of memory.

What a waste of time...

[RyderOCZ]

The memory is 2000 MHz.

You are 8 hours ahead of the office in Sunnyvale, plus your posts were over the weekend. I am trying to get the test spec for these. I work remotely from the office so I have no direct contact, only email.

When I get more information about what is going on, I will email it to you. Until then, I ask for your patience.

OCZ will RMA the modules with a set that is tested on 790i.

The modules you have were tested at 2000 MHz before shipment. The only question is, at what voltage.
Shipping, packaging, any number of things could have affected the modules during their transit to you.

[RyderOCZ]

Striker II Extreme is a no go at 2000 with these modules, confirmed at OCZ production/engineering facility.

Test, Binning, and Quals are all done with the Reference 790i boards (XFX/EVGA).

Test setup on these boards:
1.8 (2GB kits) - 1.9V (4GB kits) Memory (higher is worse)
1.4V chipset (higher is worse)
Unlinked (1333/1600 FSB depending on CPU, 2000 Memory)
P1 / P2 -> Auto
9-8-8-28 / 9-9-9-28
