Hey guys,
My PC4000 Cronus arrived today. I immediately set them to these timings:
http://www.hl2online.com/images/pc40...us_timings.JPG
250 was a breeze with 2.6v set in bios. 260, 270 was fine too. Then I went to 275 and got memtest errors, so I upped the vmem to 2.7v (set in bios, not actual). 275, and 280 were clear as bells, but once 285 came along, billions of errors. Setting TRTW = 3 fixed most of them, but I still get 800 or so errors in test #5, and I've tried loosening everything pretty much, even Dynamic Idle Counter. The only thing I haven't really tried yet is messing with the drive strengths. I just set it off to start at 7/3 like my ballistix liked and these seemed to like it too. But maybe in the higher clocks I need to adjust it? Any input would be appreciated. Either way, looks like I have a nice set that likes very tight timings.
(edit: I messed with MAL/RP too and 8ns MAL did very little for stability surprisingly, nothing else seemed to make a difference or made it worse.)
(edit #2: Bios 11/14 btw)
7ns is pretty fast for 280mhz :toast:

ah, hmm. that's odd... i've yet to really really push the sticks with a divider, as my cpu tops out around 3ghz, which is perfect for me, but i have used it a bit and didn't really have any serious problems. i do wonder what's up for you :confused:Quote:

315 Mhz, 2.7 volts, stock relaxed timings:

Also, if I keep my speed at 315 and settle with that. Do you guys have any advanced TCCD recommendations as far as timings are concerned?
Thanks.

I'll have to look for other alternatives to take advantage of these ram so for now I'm pushing for 2.5-3-3-7 at much lower memclock.
can you do 2-2-2 at 200mhz? :toast:
haven't try....running some spi32m at the moment
Try these settings @ 315. These are somewhat tight settings for 315, but your sticks may be capable of it. Give your Vmem a little boost if necessary....Quote:

i've found that my sticks will fail prime blend faster than sPI 32m.. so i've been using it to do my stability testing while tweaking a lot lately :p:
Thanks for the advice. But the first time I ran memtest I checked out a few timing configurations. My sticks do not like trp - 3 at all. I fail memtest and superpi unless I run 4. Otherwise, I can do cas 2.5 and tras 7 @ 315mhzQuote:

NP, trp3 @ 315 is quite hard to do :p: Switch it back to 4, but more than anything please note the TRC setting on my tweaker shot. If you want ANY kind of performance @ all, you'll have to change yours from 17 -> 7 (you'll tend to want to stay away from anything higher as A64 performance will be GREATLY impacted by going any higher ;) )Quote:

From there I begin to tweak. Anyhow, 315 completely stock is definitely impressive in my book. Now back to the Genie Bios..:)
PS- Keep throwing TCCD configuration tweaks at me. I am new to any kind of TCCD stick period.

Tell ya what - if you want some further help, create a separate thread and I'll follow you there ;) We've gotta stop talking about TCCD in this micron thread :p:Quote:

Ozzie, OPB, sorry guys. Let me get my azz out of here. When I find out how my Cronus sticks are doing I will post back. :D

I have some interesting findings:
I bumped my HTT to 280 and wanted to get it memtest error free, and started out at ~600 errors in test 5.
After going through the weak drive and data I found 7/X generated ~195 errors, so I decided to give 8,6/x a go, turns out 8/X gives less than 20 errors, 8/3 giving 6.
From there I started playing with the tRef values, 3684, 4196, and 4672 bringing it down to about 2-4 errors. (still test 5)
I played with idle cycle limit, 32 gives me 1mb/s more, with the same or more stability than 16, while 128 gives more errors and 256 is in between. Right now the timings are loosened up (I wanted to elimante all other variables for the time being). In BIOS my vDimm is set to 2.92 (haha high right?) but in BIOS it reports ~2.8 and windows 2.78. By bumping the BIOS vdimm from 2.87 to 2.92 I got rid of the other errors in test 5 :P I have yet to swap the sticks in the dimm slots or even try my Ultra-D
I tried bringing MAL and RP back down to 7 and 5 but IE has already crashed and hexus_pifast produced errors, so that will be going back up.
Edit: Windows stability is another story :(
Yup thats what I;m using. 8/2 strengths and 3684 tref with 2.9 vdimm. It is COMPLETELY stable. By that I mean i ran a 6 hour long stint in BF2 recently and no problems whatsoever. And that for me is as stable as can be. Borderline stability is at a maximum of 285 no matter what settings I use. With 285 Bf2 crashes at about maybe 3-4 hours.
So, to sum it up, my sticks do 280 3-3-3-8 and I guess im happy. In fact im more than happy as that is quite a good oc up from the stock 250 for a 2Gb set.
Very interesting, can you post your exact settings for 280? (A64, vDimm, DDS/DS)
Thanks man :)
i don't like memtest. it also gave me the least errors with level 8. i get better clocks in windows with 5 though :shrug:
Thank you for saying that, I was hoping someone would give some information around that. After booting into windows and getting so many BSODs I figured it was the drive str, but memtest told me otherwise, have you ever tried the custom PCMark drive str test from Eva?Quote:

I've used it in the past, it helped slightly with my Ballistix, but in our case, something like this could be key for finding in windows data and drive strengths
damn....I thought I was the only one who needed 2.92v to get this shiit stable at around 275~280. but looks like both Mikal and Tibu also have the same experience....I hope this stuff will last man, that's a lot of vdimm for such low memclock. I would also suggest you guys to bump up your vcore one more notch as well, high vdimm + low vcore = bad!!
