I do understand and appreciate your situation. It was the 2x512 kit that I'd purchased. I went through the OCZ forums trying to clue myself into what was happening. I didn't actually ship the modules out until 2PM CST, and I did check for responses right before I did so. Bottom line is that the chips weren't going to work on my system irrespective of whether they were bad or conflict. I just couldn't find any negative reviews about the combo before or after purchase and, given this is my first RMA I do expect RAM I purchase to work (I do pay a little more for better modules when I purchase and I do research them to make sure things should work). None of this is probably indicative of your company; I've read lots of very positive things about OCZ which is why I was waiting for a price point on your modules, but you understand it's personal experience that ultimately drives decision. It doesn't rule out a purchase in the future, considering the overwhelming evidence on the net as a whole to how good a company that you are, just not on my current system.

hey guys i could use some help...

i currently have a 1GB Kit of OCZ PC-3500 EB Platinums : OCZ4331024EBDCPE-K

im trying to overclock my system and have been pretty successful...

i have taken my system from 2.2Ghz to 2.7Ghz prime stable with my ram on a 166 divider.... however, anything past 2.7 is unstable and im suspecting it could possibly be the ram limiting me.

1. i have tried 280 x 10 @ 166 and unfortunatly its only 2h prime stable
2. i have tried 255 x 11 @ 166 and its only prime stable for like 10 minutes
3. i have tried 255 x 11 @ 100 (testing to find max CPU) and it doesn't even boot into windows...

for 1 my timings are as follows : A64 Tweaker SShot except i changed my Tref to 1168 and gained a lot more stability
for 2. i basically put my settings to auto
for 3. i put my settings to auto

all tests done @ 2.8v

Hello,

First....what bios are you running? I recommend the 704-2BT

Are you running in the Orange slots? You should be.

Get a fan to put over these sticks, they get hot even with stock voltage because they draw a fair amount of current, heat can affect the overclock.

Raise the Voltage to get more speed from these, try 2.9 and 3.0V.

Set your DRAM Drive to Level 6 or 8 (Normal 3 or 4 in the 704-2BT bios) and the DATA drive to Level 2

Timings look pretty good, although I think 1560 or 3120 for a Tref would be better.
Try 8ns and 6ns respectively for Async Latency and Read Preamble, also try 9 and 6.5.

Try Trc at 10, Trrd at 3 and give Trwt a try at 2.

Hope that helps.

awesome thanks for the reply, yes i am using the 704-2BT ;)

i am using the yellow slots, i guess ill switch to my orange slots (any particular reason why one would work better than the other?)

ill get a fan however during priming and whatnot i have touched my ram and it wasn't really that hot

and ill definatly change up those timings, thanks for the speedy response

Hi, I have a OCZ5002048ELGEGXT-K 2X1gb sticks. It autodetects 3-4-3-7 with 2T timings, I'm running it @ 235mhz with memory divider. After computer runs some time the blue screen comes out with:
PFM LIST CORRUPT
blah
blah
blah

stop: 0X0000004E (0X0000008f, 0X0007DCA2, 0x00000000)

beggining dump of physical memory
blah
blah
blah

Even If I run it below 200mhz it detects it as 3-4-3-6, but the blue screen comes up.

As I've read on other forums its a memory fault. How do I get it replaced?

Thanks

well just to give u the heads up heres what i tried:

- switched to orange slots

- Voltage @ 2.9, DRAM Drive @ 6, Data Drive @ 2, Tref @ 1560, Async @ 8ns, Read Pre @ 6ns, Trc @ 10, Trrd @ 8, Trwt @ 2 ::::: Prime lasted like 1 hour

- Voltage @ 2.9, DRAM Drive @ 6, Data Drive @ 2, Tref @ 1560, Async @ 9ns, Read Pre @ 6.5ns, Trc @ 10, Trrd @ 8, Trwt @ 2 ::::: Prime lasted 2 hours

- Voltage @ 2.8 +0.3 (i figured im only at 233Mhz anyway and prolly dont need 2.9v), DRAM Drive @ 6, Data Drive @ 2, Tref @ 3120, Async @ 8ns, Read Pre @ 6ns, Trc @ 10, Trrd @ 8, Trwt @ 2 ::::: Prime lasted 20 mins

not sure if that trend shows anything of importants or helps troubleshoot a bit more

Hi

Please clear your CMOS with the jumper on the motherboard. Once you done that go into the bios and manually set the timings to 3-4-3-8 1T and the memory voltage to 2.8V. Once you've done that set the computer to boot from the CD drive and let memtest run for at least 5 full loops. If you see errors right away test each stick seperatly and let me know the results

Info on
memtest here

Try more Drive...use Level 8 (Normal 4)

You are going to need more volts to get them clocked up....use 3.0 set in bios.

Again, make sure you have a fan on them.

ok well heres what ive done so far to improve temps / overclock...

A. lapped my TTBT to a 1500 grit finish
B. stripped my CPU of the IHS, now its nakey
C. placed a fan next to the PWM IC's

so far ive gained a better overclock

before : 2700Mhz MAX
now : 2800Mhz

http://uhaweb.hartford.edu/sororneja/2800_c.bmp

thats my run @ 2800Mhz @ 1.425 * 113%

if i try anything higher than that i get an error within a minute of prime, and also within like 1m 30 seconds of OCCT....

could it be my ram?

currently my ram timings are 3-2-3-8 w/ a 166 divider (so its running currently at 233.4Mhz according to CPUz)

i tried 3-4-4-8 and got better results, but failed after 4 minutes of prime....any ideas??

my max cpu temp is 46C, PWM is 47C, chipset is 50C

im currently doing 10 * 280 ..... ive tried the 10.5 and 11x multi and still a no go when i try past 2800


and also i ran memtest for about an hour on test 8 ... i think it only did like 8 tests but they all passed....should i try going longer?

Can one of you OCZ guys check the status on my RMA for me? OCZ has had my RAM for 8 days now and I still have not heard anything.

Email me your RMA number Matt and on Monday when the office opens I will check into it.

Thanks

I sent my RMA over 15 days ago from checking the status, it still haven't shipped back to me yet.
Why is it taking so long ?

Hello,

Can anyone help me with memory timings for 2GB OCZ PC4000 on an MSI K8N Neo2 Platinum? I haven't been able to find anything at the BleedingEdge forums (perhaps because the Neo2 Plat is a last-gen NF3 chipset) or by googling it. The model# is OCZ5002048ELGE-K.

Right now I have 3-4-4-8 (Tcl-Trcd-Trp-Tras) @ 2.65v on the 166mhz divider (ram runs at 245mhz) @1T. All the other settings are auto or default (is vdimm okay?) My system (see sig) is 24h+ dual prime stable by small fft test, but I can't pass blend test for 30min or oc the memory even 1 or 2mhz past stock. I have an 80mm intake blowing over both dimms, so I know they aren't overheating... I'm hoping some obscure BIOS setting will clear up these errors.

Any help would be greatly appreciated!

You shouldn't need to change any of the other timings. Start off by clearing your CMOS using the jumper on the motherboard. Once you've done that try these timings

FSB Bus Frequency............................. 250 MHz
LDT/FSB Frequency Ratio....................... 4x
CPU/FSB Frequency Ratio....................... 10
PCI eXpress Frequency......................... 100

CPU Voltage .................................. 1.400v (adjust as your CPU requires)
LDT Voltage .................................. NA
ChipSet (NF4) Voltage ........................ NA
AGP Voltage ..................................... 1.55V
DRAM Voltage ................................. 2.85V

Memclock (DRAM Frequency) .................... 200
1T/2T Timing (Command Per Clock).............. 1T
CAS Latency (Tcl)............................. 3T
RAS# to CAS# delay (Trcd)..................... 4T
Min RAS# active time (Tras)................... 8T
Row precharge time (Trp)...................... 3T

If you still can't get over 250FSB let me know and we'll do some testing of the memory.

thanks

Thanks SteveOCZ! I'll memtest and prime with the settings above. Please let me know if the changes I made (bold in the quotes) will negatively affect anything.

I may have spoken too soon about heat not being a problem.

To test, I used memtest86+ V1.6 (5 passes of tests #5 and #8 for quick stability, and then loop all tests overnight if those settings work out.)

Individually, each 1gb dimm loops test #5 @251mhz without erroring, but together, 2-4 errors crop up at ~98% of each pass of the test like clockwork.
The heatspreaders get quite warm (though still touchable), and there's barely 3 millimeters clearance between them. With a 5000rpm 80mm fan
blowing down on the ram sticks, the errors @251 clear up, but they come back when I go to 252mhz.

Could heat trapped by the heatspreaders cause these errors? I'm not sure how much more active cooling I can manage... having that intake at 5000rpm
all the time is a bit much as is. Even at stock I get the odd game crash or instance where xp "encounters an error" but the automatic reports
submitted to Windows Online Crash Analysis are corrupted.

If I can't OC my memory then I can't. I can deal with that. I just want it to be stable at stock.

OCZ, who sets the spd settings? Is it by OCZ itself?
I seen settings in spd which doesn't correspond to the rated specs but it seems to run ok when I set faster timings manually in the bios.

Yes, we program the SPD and set the looser so that all the boards will boot...basically the SPD is for compatibility, but we guarantee the rated timings.

Too any OCZ tech that can help me........I have been emailing OCZ since Febuary for ram problems......no response. i was here in this forum 2 months ago and waited for a month(no names) for an OCZ tech to email this "try the website again....." Now that i have sent 3 more emails since early June still nothing(this is putting a sour taste in my mouth). So here is my problem:

i bought 2 sticks of 512 OCZ EL PC 4000VX from TigerDirect (stupid me for not trying them out first, thought since there the best they should work) i finally got all my pieces for my build by late January (bought sticks first since i knew they were discontinuing them). First I raised the voltage to 3.0 just to get them stable on a DFI Nforce3GB, i knew in adavance these guys love juice. i kept on getting rebooting issues and i was not OCing yet. I switched out the ram with generic ram and everything is fine! its the ram, it failed memtest quickly! At first ahh no problem as i heard of OCZ great warranty on there good ram and that OCZ had a good PR. But waiting half a year is not acceptable and a month before a tech from this forum says to email the website again!
will a tech help me!

Extremely frustrated,
Catalyststs

P.S. no more PMing, everythiing will be public from now on.
