View Full Version : Got my first set g.skill LE. Worst instability I have ever encountered with memory
So I just got this brand new set of G.skill LE's. They are TCCD 0507. I popped them in loaded defaults and everything was fine. Got to windows ran some benchies, all cool.
Then I proceded to get them to their rated 275fsb speeds with the settings that kakaroto posted on his g.skill ddr600 guide. Instant crash right before entering windows.
Went back, changed a few settings that he mentioned if ram was unstable, and instant crash right befor windows. Lowered multi to 8x to see if for some reason my processor went bad or something; instant crash right befor windows.
Loaded defaults again, changed BIOS to 702-1 and instead loaded with these settings:

I can get into windows now, but she won't even pass memtest 1M.
What the hell am I doing wrong? I know I am new to TCCD and coming from 255fsb 3.5v 2-2-2-5 old school BH5, it's a huge difference. But I'm starting to think these sticks might be bad for some reason. Because I seem to be using "accepted" timings for this memory at this speed.
If anyone that has experience with this ram can suggest ANYTHING to get the ram stable, I would greatly appreciate it. Because right now I am clueless and getting more frustrated by the minute. :(

I would try TRCD 4 and TRRD 3, and 1ns more both in Max Async Latency and Read Preamble.
BTW, nice avatar, Spike rocks!! Cowboy Bebop was one of my favourite animes ever :)

Yeah but remember this ram is RATED at 275 2.5-3-3-X. For now I'm refusing to up the TRCD to get it stable at 275 cuz then I would just RMA the sticks.
And Cowboy Bebop IS the best anime ever... after Evangelion :p:
Anyone else have any ideas?

put your vdimm @ 2.7v for the helluvit. 2.8 isnt healthy for tccd anyway.
also try having a fan blow on them. tccd performs the best under 40ºC.

I think this ram is bad.

I don't think it's as bad as you think... If they were bad-bad, you should be getting "Memtest for Windows" errors much sooner...
1. Start with 2.6v
2. Try settings like here (http://www.clockmehigh.com/cooler/screens/3700SD/Gskill4400LE_HS/285x11_3135Mhz_memtest500_edited.png). TRC=7 or Read Preamble=5ns is fine as well
3. You can try rotating modules.
I originally had them in the orange slots when windows wouldn't load. So I inverted them and switched them to the yellow slots.
I'll try and switch them back to the orange slots and maybe try 704-2bta bios again.
BTW Bachus, do you know if G.skill will honor the warranty if I can;t get them stable at rated speeds, even if I bought the sticks new from a member here on the forums?

BTW Bachus, do you know if G.skill will honor the warranty if I can;t get them stable at rated speeds, even if I bought the sticks new from a member here on the forums?No idea, that you would have to ask G.S Technician about. But maybe it's just a bit too early to say they are bad. Keep trying ;)

Well I guess it's an improvement but still...
Changed to 623-3, orange slots, 2.6v ram. Any ideas anyone? I think I'm running out of options.

Changed to 623-3, orange slots, 2.6v ram. Any ideas anyone? I think I'm running out of options.That screen tells you that your RAM is most likely just fine (180% is good news). You need to remember that many TCCD-based sticks are not entirely plug-n-play and they need tweaking to get them to work on different setups.
Set LDT and Chipset voltage to 1.2v/1.5v respectively,
Set TRC=7, MaxAsyncLatency=8ns,
If that does not help, change Drive Strength=7 and Data Strength=2,
If that is not helping, up vdimm by 0.03v by enabling "DRAM +0.03v".
Ok, I tried trc =7 and async latency =8ns and it errored before 10%. Went back to trc 9 async 7ns and enabled dram +0.03v and it errored at somewhere around 130%.
Went back, disabled it and instead changed trc = 7 only and got this:

It's a great improvement to say the least. But still i was hoping to get at least 300fsb out of this ram and it is barely stable at 275 rated speeds...
Anyways; thanks for all the help bachus. I really appreciate it man. I can at least use the computer without crashing at 275fsb. I'm gonna keep tweaking and see what happens.

300MHz 6-3-3-2.5-1T is quite pushing it, you know. Some kits will do that and a bit more (my LE is M4W, SP2004 @ 301 6-3-3-2.5-1T, 2.8v BIOS) but that seems to be quite a stretch for it.
Note that you are still @ 2.6v. Those sticks respond the best in range of 2.5-2.8v so you still have some testing to do. Try few different Tref values (Auto, 3072, 3120, 2336, 4708, 1816, 3684...) MaxAsyncLatency, Read Preamble and Drive Strengths may be very, very crucial to achieving stability... Your RAM seems to be fine but it's just had to say how far it will go.
Welcome to TCCD-land! It's a whole different animal compared to old BH-5 where you just pop sticks and and they work by themselves :D
Good luck and keep trying :)
It's funny but this ram HATES drive strength at 7; Insta crash at loading windows screen. While almost everyone is running 7/2. Kinda weird ain't it?
Anyways here's the latest:
285fsb winmemtest error @ 40% (http://photobucket.com/albums/v428/Tibu/?action=view¤t=285fsbwindowsmemtesterror40.jpg)
Playing with settings to try and get it stable at 285.
Well I have tried for three days to get the ram stable using every possible combination of voltage, bios revisions and settings and it still is not close to stable.
I managed to get it to pass windows memtest till 600% and then it threw an error right at 600%. But when I went to run Superpi 1m... It failed before the initial value was finished.
There is just no way around it. The ram is defective IMHO. I would understand if I had these sorts of problems at 300fsb, but not at 275. No matter what timings I use, not even 2.5-4-4-7 will get it stable at 275.

If you want a suggestion from me, for what it's worth, try the 510-3 bios. Since you have a venice chip you shouldn't have any issues. I used this bios with my LE's and was running 305x9 stable with 2.5 4-4-10 2.7v. They also did 275 2.5 3-3-6 2.7v stable. With any other bios I have had nothing but problems with this ram.

maybe its not ram, try a lower multi and see how it goes.
i have the same ram (diferent week on the chips) and i can get them higher but not with the same setting as you but now i get bsod at default setting in bios but i run everything at 2500mhz rock stable
I gave up on the sticks and returned them to the person I bought them from here on the forums.
BTw it isn't my processor as I am right now running it at 2.8ghz on air with my old school BH-5.

I have the same week chip on my G.Skill LE. And have been getting the same thing. Random BSOD and stuff. I will try the setting above. And this was at 210HTT using the setting posted by kakaroto. Using the orange slots, bios 704-2BTA, 2.7v . Im going to try some more setting be I decide to RMA them.

When you when cannot set Drive strength at 7, this can indicate a weak controller. The drive and data strength are different per CPU.
The easiest way to test is in single channel. Normally those timings must work 100% with 1GB LE.
if you previously had other memory in the board, do a full CMOS clear and do not use a saved "BIOS reloaded" setting. Let it autodetect out of clear CMOS, then do everything by hand.
If you haven't, use the 623-3 BIOS. For me, it detects TCCD very well and places it at almost optimal settings. Basically I only have to set TREF to 133 or 100 MHz for better speeds.
What kakaroto said, test individual sticks but keep in mind you must use slot 2 for this. Slots 3 and 4 on the DFI NF4 boards don't do single-channel (at least not for me).
Do not copy other people's memory settings. The CPUs are too different. The above BIOS probably comes up with better values by autodetection. MY BH-5 memory for my 939 Opteron with Geil One BH lead another user of a similar Opteron and the same Geil One BH to nothing but a crash hard enough for a CMOS clear (which is rare on the DFI boards).
