hmmm, i have some week 437 LE sitting around, when i get my new mobo in, i should try to get 300mhz.. i can do it in memtest now, but not in windows. :slapass:

got my new pair of 4800 1GBFF's (rma replacements)

Passed superPI 32M with settings for 275mhz @2.6v , it failed within 1 minute with 285mhz @2.7v...tried 2.8v but failed 20mins into superPI 32M. I'm just trying to get 285mhz at 2.5-3-3-7 because that matches my max cpu OC.

What should I try to tweak at that point since you just increase volts and passed? Should the recommended tweaks be done one at a time, or all in one shot, or mix and match?

Thanks

they are very sensitive to TREF and MAL/RP from what i've seen...since it responds to voltage you can use 2.9 but it isn't looking like it's gonna get there unless you just have a TREF on there it really doesn't like

try 2.5-4-3-7 1T.....would be interesting how far they go

Maybe an off topice question here, but do the different weeks of ram production make a difference like weeks of a cpu? Slap me if I am asking a Noob question! :slapass:

It depends, some weeks are really good and some are bad. But overall all TCCD are good.

cannot get 284mhz stable

Well I'm still trying to get 284 stable at 2.5-3-3-7. That is my max cpu mhz so I'm not even trying 300 with 2.5-3-3-7.

I have F1-4800DSU2-1GBFF rated 275mhz at 2.5-3-3-7 and 300mhz 2.5-4-4-8. I do not know what TCCD chips they have because of the heatspreaders. Just got em back from gskill rma they claim to be a new pair.

Started off with 275 @2.6v - 2.5-3-3-7...superPI fails instantly.
Switched memory banks - 32M fails after loop 2 (2mins 34sec)
Upped vdimm to 2.7v - 32M completes in 29min 20sec

Try 280 with same settings - 32M completes in 29min 12sec
Try 284 with same settings - 32M fails instantly
Change trcd to 4 - 32M fails instantly
Dont know which settings to change at this point, I've tried the ones listed under the If your memory is not stable try this: area of step 3.

Any suggestions for my memory?

EDIT: 284mhz at 2.8v 32M passed at 28min 32sec
Testing with prime blend test overnight, failed 3 minutes into test.
Testing with memtest in windows, all unused ram...update on sunday morning: rebooted from a bugcheck

@Modulok: If i am correct your memory reacts good by upping the Vddr.

Is 284MHz 2.5-3-3-7 completely stable now for 24/7 use? (SP2004 RAM Stress)

Im using 280x9 now, stable in games and 3dmarks. Need to test overnight with SP2004.

Stable:
-8hrs large test of prime95
-memtest in windows 280x9 overnight with screen saver off
-32M superPI
-trying memtest 284x9 right now

Got Bugchecks when trying memtest in windows, possible it happened when screen saver came on.

Unless you [kakaroto] give me other settings I'll stay at 280.

Thanks!

well yeah, they are the ones you posted.

If memtest passes today at 284 Ill try sp2004 tonight.

Think it's possible for the screensaver crashing system while memtest is going on, ie the bugchecks I got.

What about the prob witg DFi expert and TCCD 600?

I have try get 2.5-3-3-7, but the max i can stabilise is at first 275-280mhz with 2.5-3-3-7 ( OCZ 4800).. then i need up at 2.5-4-3-8 (1T).. but i know the G-SKILL work differently of OCZ..( i think.. pehraps i make a misstake.)

I try stabilise now at 310 ( or 320)x10 ut really without divider it's impossible I can't have same settings like i have use with my DFI SLI DR...

Some advice in Tref or Data drive strenght?

I also have a feeling that this only applies on newer TCCD's which operate better with a higher voltage.

I have change my board just now.. for SLI expert ( biosE704-2BT).. seems have some issue with TCCD.. strange thing the board is really more stable of the SLI DR... I will give now some try of your settings and take al of this with a lot of considerations.... Thanks..

Edit-..r eading some thread i see you use too SP2004.. seems some week i see ont thing o my OC.. i can stablise an OC at 3150 with SP 2004.. but it's not Super Pi 32M stable after... looking temp during test, i have see the SP2004 should don't really stress the CPU or DDR cause temp don't heat so much as during Prime95, Super Pi 32m, or OCCT... do you think it's better finalise stability with Prime95 ?

Trying to get my week 440 g skill la at 2.5-3-3-7, with no joy so far!
Strange thing though, my pc wont boot with the ram in the opposite slot to the one there in now ,module one in highest orange slot & module 2 in lowest orange slot works fine, swap them over and i get no boot even with clearing cmos??
I get no errors with super pi in windows though and performance seems normal in games and stuff.

Did you mean trcd 3 is hard to get as mine works fine with trp 3, trcd 4 but not the opther way round.

Well memtested for more than 12hr yesterday without errors.

While in windows not really doing anything I got a bsod, irq error and memdump. Not too sure if it was memory related. Tried SP2004 last night, it failed with another bugcheck in system event log. I'll try 280mhz with sp2004 later today.

That is weird indeed, I had that ones with some modules. Just install them in the best way.

Mostly with TCCD tRP 4 to 3 is very hard at DDR600. tRCD 4 to 3 is offen no problem at all.

Does PC3200 OCZ EL Platinum Rev2 v1.1 (TCC5) have any chance running with these settings or even lower (more like 280 HTT)? It seems i have tried everything but I can't get them to run with 2.5-3-3-X at even 252 Mhz (280 HTT with 180 divider)?

I have same problem with my G.Skill F1-3200DSU2-1GBFX 1GB (2x512) PC3200 'TCCD' 2-2-2-5

Cant get stable @ 2,5-3-3-6(7) over 265htt X10. Raising volt didnt help too. Have to use 180 divider then i get 280htt stable with 2,75v. And i have dfi ultra-D with opty 146 :(
I really hoped to get at least 280htt with 1:1

I tried sp2004 with 284 and 280 but it rebooted pc with bugcheck.

Which specific test should I run in sp2004?

I tried prime blend test with 280 at 2.83v and it passed 9hr+.

For RAM I suggest Large FTT's for some hours if that is possible.

If using a dual core do I need to run dual instances (I do for cpu stability, but not sure for memory)?

Also, thanks for the guide I was able to get my Patriot PC4800 XBLK, dual SPi 32M stable at 295 2.5-4-3-7 1T with actual vdimm 2.866 (bios setting 2.92, expert undervolts, but reports 2.87 in bios). I also set my DS, DDS both to auto as I was having trouble with your settings.

Could you explain dqs skew?

Are drive strengths weak when odd and strong when even AND the higher the number the stronger?

Thanks for the guide, my GSkill GBFX can do 290Mhz 2.5-3-3-7 1T 2.7v

now, try to get 300MHz, upping vddr to 2.8v still no go
Any advice?
03-19-2006, 01:24 PM
kakaroto

If upping Vddr does not gain you stability, you can conclude two things:

1. the chips cannot handle DDR600 with your set timings
2. there is no OC headroom left

The main timings are fine and should not be more looser.
Try more DrStr (drivestrength) and DaStr (Datastrength), 8/3 or 7/3.

What you also can test is lowering the DrStr and DaStr and up the vddr to 2.8v.

Try 9ns MAL and 5.5ns RP.

You can try this all. Reply back if this does not solve it ;)

I've got a pretty nice set that does DDR620 at 2.5-4-4-7. What are the chances I can do DDR600 at 2.5-3-3-7?
