Bandwidth screenies. Not bad huh?

 

[g0dM@n]

Tref 1168 (166MHz, 7.8us)

How is that 166mhz? I thought that the cycle time is 7.8 * (freq). 166*7=1295... in any case, why would it be set to 166 when that ram is rated ddr400~ddr533, and also you're running it at 300mhz 1:1... I'm confused as to how you came up with that cycle time. Care to explain?

Nice, btw... I had the same stuff until I sold it.

Take a look at my A64 tweaker screenie. That timing worked for me, so I decoded it to tref=1168 from the memory sticky at DFI-Street.

Man, you shouldn't have sold these modules. They will become a collectors item, like the BH dies. I have 2Gigs and can afford to get rid of one if I''m in a tight spot.

Extra Notes and observations:

Above 215 Mhz DRAM frequency Memtest86 produces errors in Test #5 and #6, if CPC is enabled. (1T) I wonder if there are some settings which would help me pass this barrier. Right now the system is Prim 95 stabel (24 hours) and Memtest can loop with no errors.
I aimed for 2400 Mhz, I did expect more from this pair of DIMMs, than again, it might be the memory controller.

Apparently Nvidia nTune is silly. it says I have 474 Mhz mem frequency, which I know I don't (BIOS, ClockGen, CpuZ all say 215 Mhz)
Also my PCX appears to have 2500 Mhz ???

Hubert,

Try the latest Forceware drivers. The ones that came with the MoBo CD are a bit old. Since you have TCCD, I'd recommend setting the CAS to 2.5 and running 1:1 i.e DDR400.

I dont know why I cant get 1t with any settings and its not because I have 4 sticks of mem either because it acts the same. Basically it wont post at all even at stock speeds. The other thing is that this memory will not post if I change the CAS in either direction. If anything I would like to tighten the timimings a bit but nothing seems to work at 2-3-2-7 if above 225mhz.

These settings took me some time to get stable but have since been happy with the result, apart from the fact that after I reapplied AS5 on my heatsink, and having to remove the powercord, I am now beeping again and back to 512mb.

I am also wondering about this 6/23 bios. It worked great until my hesitated decision to unplug the power cord. I here that the 5/10 bios is very effective for cold boots but have not tried it yet. Have any of you tried these two bios's. Ive done 3/10, 6/23-2, 7/04-2, 6/23-3; in that order. Feel free to suggest another version. Thanks all

 

[ShadowClock59]

I have also tried different bioses, currently I am using the 6-23-05 final.
This Bios is far better for my San Diego than the 310p, however I no longer have a NC core, so comparing these is not an option right now.

But, I can help with the Ram some, also if you have changed multiple Bioses and have gotten a lot of errors through testing, then a fresh install is a must!

Tref is a critical setting, try setting it using this formula 7.8 ( For Dual sticks 15.6 for single sticks of Ram) x 262 (Or any HTT VALUE) = 2043.6 find the tref value closest to this number and use that one. I got this from the XS forum and it really helped to stabilize my OC. Here check out the results from using the 6-23-05 Bios and a fresh install of XP Pro.

Extra Notes and observations:

• - Surprisingly, These settings go against most of my observations with my other sets. The most important point was that I had to reset the CMOS before even switching back to 512 x 2 from 512 x4 ! With the same settings, I kept getting BSOD's. When I reset the CMOS, boom.. 32M stability!
  
  Please reset your CMOS if you change modules.
  
  - Note that my bandwidth is about 600 points lower than those who have 2.5-3-3-x settings. The tREF timings also contribute to a BW loss, with the 1.95 us settings > 3.9 us etc in terms of Bandwidth scores.

Not much activity on this thread but it seems like the most relevent place to say I got my new computer and have updated my signature with some preliminary results. I'm pretty happy with the results so far.

 

[ocing newbie]

**UPDATE**

I installed a dynex 34cfm fan to give active cooling to my ram which had gave errors at 265mhz but now it is stable at 265 for over 80 passes of test 5 in memtest. My signature is updated with my current settings. I'm priming currently but have been getting rounding errors. I thought I'd set the vcore to 1.525 but I checked this morning and it was 1.5 so I put it back to 1.525 and I think it should be stable now.

**EDIT**

Had to raise the vcore to 1.55 but it's priming like a champ now. Now I have to debate whether to mess with yellow slots, bios changes, and other bios settings to get memory a little higher. I should probably run each stick by itself to figure out what's holding me back.

[Super Nade]

Mate,

First off, update your system to the latest NF4 chipset drivers. Do not install the IDE Drivers. They are known to cause system instabilities. What chips are on your RAM? Is it TCCD? If so, I'm quite sure you can push it a bit more than your current frequency.
Try 7 and 2 for your drive strengths. How far can you go in memtest? Spend the first few day's tewaking the settings in memtest, before you jump onto Windows.

Whan I get new RAM, I find a reasonable OC first, ensuring that it is stable in Windows. Save that as your everyday setup untill you can optimize your timings. Next, use memtest to determine your best settings. Start with one timing at a time.

Set the timings to 2.5-3-3-10-1T first.​

Now, optimize all other timings as you slowly increase the HTT in 5MHz steps​

Once you hit a wall, say at 275MHz, loosen the tRCD to 4​

Resume tweaking. You may see that loosening timings may actually induce more errors! This is because one cannot think of the timing parameters as being mutually exclusive. Drive strengths and tREF timings are easy to set (wrt the fine timings as opposed to the coarse ones i.e CAS,tRCD and tRP) as they put out the most errors if incorrectly set.​

Keep an open mind and don't hesitate from trying BH-5 parameters as well.​

Deending on what kind of chips your RAM have, you may ned to bump up the DRAM voltage​

Hope you have taken the CPU out of the equation (initially) and lowered the LDT appropriately​

*Run time and diagnosis*
I always run memtest #5 for 30 min and make a note of the # of errors. Run the test for 30 min regardless of the errors. Error count is important in determining how a particular setting has influenced the whole process.

Once you see no errors for 30 min, its time to bump up the HTT
At the end of the day, let memtest #5 loop overnight. If there are no errors...

You should also read sucka's guide on memtest stability. <See his sig>

Good Luck!

[KroxX]

Thanks for your nice and thorough reply!

I just remembered that I installed version 6.66 from nvidia.com. The latest version from DFI is 6.53. Should I stick to the 6.66 version or go for 6.53?
I did install the IDE driver though, just not the ide-sw one. Will reinstall it now.

I have no idea what chips are on my ram, and apparantly nobody else has either. It has been suggested in this review that it might be Samsung TCC5. "speeds of up to 433MHZ [at 2-3-3-6] OR DDR480 above [at 2.5-4-4-8]…” - According to that review that is what the g.skill website claims. Everything else I've read about them indicates that they might be micron, hynix, mosel or psc. They don't like high voltages, anything above 2,8V is pointless.
I got it memtest & prime stable @ HTT: 243. Then I decided that it was enough. I wanted to run some benchmarks and see what progress I made so far, before I continued pushing it.

What I was really curious about was why I could get both the CPU & the RAM completely stable individually, but when I put em together, suddently it wouldn't even begin to load windows?!
I suspect that it might be the Tref that screwed it up when I put the ram on a devider..

Thanks,
KroxX
