OCZ DDR3 4GB Kit OCZ3P16002GK

[malkiewicz]

Anyone else having problems with these...

When I tested them at 1600 w/ my system default settings 9-9-9-24 (Memtest Passed), but when I use the manufactures recommended settings 7-7-7-24 w/ all other system settings on auto as indicated below (Memtest had tons of errors)...
Truthfully I would like to get a little more out of these… I expeceted more from OCZ, but I’ve also heard it’s difficult too OC anything over 2GB…
Current Bios Settings...

dram voltage = auto?

you need to back the CPU down to stock to test starting at 1333, the load quads place on x38 and X48 is massive and yes you are right in saying its hard to clock 2GB modules.

transaction booster needs relaxing and you may see NB voltage at high as 1.6 to get things stable.

Its a whole new ballgame with quads at 400fsb and 4GB over 2x2 dimms. 790i does it well but X38/X48 is not as good.

You many want to try 1333 with tight timings, its a lot easier to do and will allow you to get the CPU where you want it. i was running 6-6-5-18 in a premium board to around 1400 with sensible voltages.

To finish, if you had a dual core in there the ram would be doing a lot better, its the quad that is causing the issue.

[malkiewicz]

Wow, I would hate to run them a @ 1333 (Rated at 1600).... I just replaced my 4 GB of Team 1333's that would run at 1544 7-7-7-20... Looks like I'm going to RMA if I'm forced to reduce performance

Memory voltage at Auto?

That will result in 1.5v for the ram. Set that to 1.8V, then try at 7-7-7 at 1600.

[malkiewicz]

Sorry about that...

Update:

Read/Write - Disabled
Ram Voltage - 1.84
Booster - Relaxed (2)

Tested

Read/Write - Disabled
Ram Voltage - 1.80
Booster - Auto
NB - 1.55

[saaya]

errors in test6? hmmmm

what memory slots are you using?
try 2 and 4
go for 888-24 to make sure the fsb is stable, if that works, then go for 777 again and try to find the sweet spot, remember more vdimm isnt always better

if 1600 888 doesnt work then try each stick individually, you might have a bad stick, or maybe your cpu cant do 400fsb stable?
drop the multi to 6x to check this.

[malkiewicz]

Tested : 8-8-8-24 @ 1600 for 2 hours w/ no errors

Read/Write - Disabled
Ram Voltage - 1.80
Booster - Auto
NB - 1.55

--------------------------------------------

Tested : 7-7-7-24 @ 1600 (1st test passed, but the 2nd, 3rd & 4th failed - same as above)

Read/Write - Disabled
Ram Voltage - 1.80
Booster - Auto
NB - 1.55

I'm currently using DIMMs A2 & B2 (I guess you can call that 2 & 4)...

[kiwi]

Tried each stick alone? 1 stick, cpu 6x400, ram 1600Mhz, 7-7-7-24 1.8-1.9V, NB 1.6-1.65V, dram command rate 2T

And don't touch transaction booster yet

[malkiewicz]

Yeah, I'm testing single sticks now... Just had my first one fail (The sticks have a sticker that indicates 7-7-7@1.9v?)

----------------------------------------------------------

1st Stick Tested @ 7-7-7-24 / 1600 T2 (Passed Twice)

Read/Write - Disabled
Ram Voltage - 1.86
Booster - Auto
NB - 1.61

-----------------------------------------------------------

2nd Stick Tested: 7-7-7-24 / 1600 T2 (Failed Twice)

Read/Write - Disabled
Ram Voltage - 1.86
Booster - Auto
NB - 1.61

[malkiewicz]

Thanks for every ones help ... Looks like I need to RMA... Bad Stick

Update - Re-tested the one that passed again

1st Stick Tested @ 7-7-7-21 / 1600 T2 (Passed Again)

Read/Write - Disabled
Ram Voltage - 1.86
Booster - Enabled / Boost Level 2
NB - 1.56

Too bad the other stick has errors...

[kiwi]

OCZ has excellent support/RMA services so no worries

[Tony]

I still feel I need to remind you guys that quads add a ton of load to NB chipsets, specially when the CPU is overclocked. I found using 1 dimm was able to pass tests but the load of 2 dimms and the quad with 400fsb pushed some chipsets to hard...and I test a few boards remember

All these huge clocks on DDr3 are with 2GB kits and E8500's, makes you wonder why

790i is better than X48 with 4 and 8GB though, so there is hope

Hey Tony, by huge clocks, do you mean high freq or high load on NB:..?

I would say that one puts a pretty hard load on NB... But then again, if its high freq that counts, it doesnt... I must admit, Im not fully aware how NB is effected by number of cores etc... I have to do a little study

[Tony]

you have a 2GB kit there, much easier...the issues are with 4GB spread over 2x2 or 4x2 for 8gb.

[M.Beier]

Oki, yea, sounds reasonable...
I hope to get 4x2GB soon, would love to do some testing...
But is it because of the ram or the NB:...? If you have access to the gear, can you give it a test on a RAM-tester... ? (simmtester)
OCZ must have some...

[RyderOCZ]

Maybe v3.4a has it fixed, but I found 3.3 and early 3.4 to give errors where other memtest did not.

v2.01 from www.memtest.org is still what I recommend for testing memory outside of Windows.

[tekjunkie]

I had the same problem on my 2x2 EB sticks. When I run them @1600 @ 7-6-6-24 2T(the rated speed and timing) Memtest 2.1 showed errors. This is on 790i(S2E) and memory @1.9V and SPP @1.4V. They run 1600 7-7-7-28 2T fine. ALso, I have a lot of system freezes running everything @ default except for memory and SPP voltage. I am RMAing it through mwave.

[malkiewicz]

Yeah, OCZ recommended that I use Memtest86+ 2.01 (This version recognizes my chip sets and runs smoother/faster IMO), but I’m still having the same issues/problems... I wish I could keep the good one and replace the bad one (1 for 1)… I dread getting a new kit with the same issues…

we are only talking about 1600mhz here, not even 1800 or 2000 and beyond...

from your comments on 790 i take it you have one of two of those special boards nvidia sent out to its partners and reviewers ^^
Try a retail board or two and then tell me again how great 790 is

malkiewicz, try less vdimm, some sticks like more or less vdimm
that one stick might not be faulty, it might just prefer lower vdimm
and if its faulty, im sure ocz can change it quickly

[malkiewicz]

I've decided to return my OCZ ram kit, and I'm thinking about replacing it with the G.SKILL 4GB (2 x 2GB) DDR3 1600 (PC3 12800) Kit... Its rated at 7-7-7-18... Question - anyone know if this will perform at the rated speeds... I've seen nothing but good reviews... Thanks...

[chris.y2k.r1]

I have the 2 gig Kit with an E8400 and these sticks have been by far the hardest part of my system to setup. 9 9 9 will run at 1600, 7 7 7 is a bit of a challenge. I've also noticed that these sticks don't like anything about 1.86/1.88 at any speed or latencies. 3 months later and I'm still battling it out with these sticks. I've been writing down all my settings... I have pages and pages of notes as the ME is a picky ass board too. I must admit that my luck as far as clocking goes with OCZ memory has been pretty shotty but I've never had a problem with OCZs service. I"m quite happy with my 1010W poiwer supply. That thing has been great.

[saaya]

maximus xtreme, yeah, all rog boards i ever used were a bit picky and not easy and predictable to tweak. i looooove the REAL asus boards tho
p5k deluxe
p5k3 deluxe
p5k vanilla
p5k pro
p5k premium

all great boards
Ive heard of many people having problems getting 2x2gb 1600 777 kits stable... it seems its not plug and play for all people...
If thats really the case then i dont think it makes a big difference what mfg you buy your kit from, you might just have to try several kits to find one that works well on your board. with ddr3 there are some weird compatibility issues, some kits work great on one board and suck on another one...
id say give ocz a chance to fix this, im sure they will
if the rma kit still doesnt work, go and sell the kit or return it to the shop and try another kit...

I tried the GSKILL 4GB DDR3-1600 Kit when they just appeared at newegg. They are stable on my P5E3 Deluxe at 7-7-7 1600 @ 1.92v. They can pass memtest @ 1.70v, but need 1.92v to pass 4x superpi 32M in windows.

However, my $200 2x2GB crucial value DDR3 8500 kit is stable (in windows) on the same board at 7-7-7-18 1600 @ 1.72v.
