Bh5 Stuck at 240mhz

[kryptobs2000]

memory in my sig, can't get it past 240mhz no matter what on my dfi 250gb. At first, it was because I was using sata port 1, but i switched to #4 and my hdd would still crash. Then my bios started acting wierd, well, really the only problem is memtest just wouldn't work, and it used to. I reflashed, same problem. So I tried the.. I think the 9/14 bios, or something. The first beta bios. It works fine, hdd no longer crashes.

However, I'm still stuck at 240mhz. I can run it at 3.1v stable I think (failed prime after 2 hours, but proc. needed more voltage. I know it's stable at 3.2v and right now I have it at 3.3v.

Highest my vdimm can go is 3.44 because my 3.3v rail is about 3.65. I have tried 2.5-3-3 with 2t and 3.44v and still I cannot even get stable at 245mhz for more than 20min. Have I just reached my limit or what? I would like to get at least 250mhz. Also, I tried each stick by itself, and still no go.

One thing I did find really wierd, when I was tweaking my memory timings, I have to reset the cmos I set everything as seen in these screenshots (which I now run 24/7, 5hr's prime, and 32m stable). And it would boot up, but it would not load windows, I wondered why, so I went to check in the bios, and saw they were only givin 2.6v I'm really surprised they even booted, just wanted to share that lol. Anyways, how does everything look overall, and Any suggestions I might be missing, or is somehow the mobo (or maybe even the memory controller) limiting me. Never heard of any problems with the 754 NC or CH memory controllers but mines a cbasc 04/16.

edit: I have a 80mm fan on top of them, and the heatspreaders are removed if it m
atters. also, I havn't ran memtest for more than 30min or so. Oh and I forgot, another problem I switched the bios is because I used to beable to boot at 270mhz w/3.44v 2-2-2-5 1t everything else on auto, and it would fail memtest in about 5-15 min. I could no longer boot at anything higher than 250mhz. Havn't tried booting anything higher than 250mhz since I flashed it, so I'm not sure. I will run memtest overnight at 250mhz and see if it's stable. Also, whats highest voltage I could put my 3.3v rail at 24/7?

here are the settings I use for 2x512 BH5 @ 260MHz, 3.4v

**Dram Frequency Set(Mhz)**= 200(Mhz)
**Command Per Clock(CPC)**= Enable(1T)
*Cas Latency Control(tCL)**= 2
**RAS# to CAS# delay(tRCD)**= 2
*Min RAS# active timing(tRAS)*= 10
**Row Precharge timing(tRP)**= 2
**Row Cycle Time(tRC)**= 8
**Row Refresh cyc time(tRFC)**= 12
*Row to Row Delay(tRRD)*= 2
*Write Recovery Time(tWR)*= 2
*Write to read Delay(tWTR)*= 1
*Read to Write delay(tRTW)*= 2
**Refresh Period(tREF)**= AUTO or 1168
Write CAS# Latency(tWCL)**= AUTO


*DQS skew Control*= increase skew
*DQS Skew Value*= 128
DRAM Drive Strength**= level 2
*Max Asynce lantency**= 8ns
*Read Preamble time*= 5ns
*Idle Cycle Limit*= 16cycles
*Dynamic Counter*= enable
*R/W Queue Bypass*= 8x
*Bypass Max*= 4x
*32 byte Granulation= disable

of course, all ram is different and the cpu mem controller can play a part, but it should give you an idea if you want to try changing anything. Try 1 stick on it's own and see how far it goes, 2 sticks limits my overclock somewhat.

edit: btw, I also have that problem where the mobo won't keep it's voltage settings... sometimes I need to go into bios, save and restart, or sometimes I need to clear cmos. I don't know how to solve the issue, it's very annoying.

[kryptobs2000]

well those settings decreased my bandwidth by almost 100mb, but I can now get to 255mhz at least somewhat stable. 16m superpi at least. 260mhz I get 100+ errors in memtest #5 on the first run tho :(

Bandwidth is now 3860mbps I'd like to get 270mhz but I doubt it's gonna happen and I didn't think it would. I'm just aiming for 4000mbps tho maybe I can get it if I tweak my timings more.

[andL64]

yeah should be better but u ll need much voltage 3,1-3,3 is good for 250+ but for 260-280 u need much more... i got the ddr booster but it show 4V really its 3,8Volt

check this out:

[kryptobs2000]

ur bandwidth looks pretty low for 275mhz. I dunno if it would matter that you only have 1x256 but I'll post a pic of mine at 255mhz. And since I got 2x512 it'll be alot harder to get 275mhz than 1x256 if it's even possible. I'm not planning to get it, just what I'd like to get. You think it'd be safe to give it 3.7v 24/7?

edit:
I get about another 100mbps every 5mhz, and in cpuz, my vcore isn't really that low, it either fluctuates or the mobo isn't very accurate.

u got pretty low timings maybe u should tweak em somehow in the amd64 tweaker.

my score is low just check the amd64 tweaks on my pic u ll see u have it much tighter also this 2x256 r only 4 benchin...

but i think can do some more i burned them to fast with to much volt they ve done 255@3,1Volt :D so maybe if i only get them 3,6-3,7 i ll go higher but @ 275+ it ll be very unstable.

hmm i dont know didnt run long @ 3,7+ only for benchin and so.... but with a fan blowing over it it should work!

seEn andL

[kryptobs2000]

yeah, I know, my timings are pretty tight, but strangly, if I run memtest #5 at 260mhz I get between 2 and 16 errors, and if I loosen them up, I get about 100+ errors. So for some reason it seems more stable at tighter timings. This isn't all of them, and it's mainly if I put the configuration settings at things that should be more stable. But I get about another 100mbps by keeping those tighter and then I somehow gain stability. And about the normal timings, most of them don't make much of a difference for me.

Nice how at 265mhz tho, I'd be getting the same bandwidth as you, and urs are pretty tight too.

[andL64]

but just look at my tight 255 tweaks its only little difference

[kryptobs2000]

This morning after posting my last post, I tried tightening my timings, I went to school, left prime running, and came home to find it hadn't failed (3 hours). And this is now what I am running and only at 3.44v still. I'm pretty impressed, specially considering I couldn't get over 240mhz, I don't know what was keeping me back but nothing is now, can't wait till I throw 3.7-3.8v at this :p:. It would be really nice to get 270mhz specially with these timings. I think this thread should really be moved to xtreme overclocking soon :D

What voltage are you running at andL64?

[andL64]

for 255 3,1 Volt in real but the booster shows 3,3 maybe i ll get the ocz powerstream 520Watt PSU with adjustable rails :P

seEn

PS: very nice clock! some ram (bh-5;bh-6) need to be "burned" some time with much voltage then they ll be very good @ work :D

I pump 3.6v through my BH-5 24/7
It's able to do 270 stable, but I run my cpu @ 1.55v @ 10x260 24/7 :)
No problems whatsoever, just add a fan for a bit of fresh air though, the airflow may or may not help but it won't hurt the ram either ;)

[kryptobs2000]

Well I'm having a few slight dissapointments. 1st is, while running superpi 32m and 60 loops of lobby high, comp will reboot after about 30 or 40 loops. But thats with the really tight timings. 2nd is I upped my 3.3v line to 3.95v (ovp kicks in at 4.05 or something), and I think the problem is related to that I'm not sure, but if I restart the computer will not turn on. So basically I just have to shut down and turn it back on manually. Does that sound like my psu? I tested while running lobby high, and my rails are stable as a rock still tho.

5v > 5.25v
12v > 12.52v
3.3v > No idea... cause I can't read it lol dfi always reads it .1 lower than it is tho.



However, good news. Tried 3.6v and I managed this. It's at least somewhat stable. 4 passes of memtest #5 10 loops of lobby high, and 1m superpi benchable. I'll test for stability more later though. Right now I'm just worried about my psu (if thats whats causing the restarting problems).

At 3.7v I could not get 270mhz stable, I got 1500 errors or something in memtest #5 on the first run, with 2/2/2/10/10/12 timings :(

Also! I should be getting my 6800 gt back today, so I can run some 3dmarks and crap :)

[andL64]

ok nice but....

here we go dude :)

pics say more than words...

( like ur timings "r" but 16x ! )

[andL64]

uhhh sweet eh?

check everst on 277,5 (very tight) :D

hmm they r to big lol instead of 200 they r 203-204 *lol*

ok so no everst pics :D

[kryptobs2000]

I did show pics lol, what d'you mean pics talk louder than words?

What voltage did you need to get that, and I know it's not stable lol, you said the 275mhz was barely stable, but still, that 280mhz.... nice :) I can't get mine 100% stable at 265mhz still, and I dropped my 3.3v rail down to 3.85v and I still have this problem with it not wanting to restart. I've never tried 16x either, by running the timings as you saw, vs. the earlier, I only gained about 15mbps or so lol, I'd say it's not worth it. Other than the fact that it just looks nice and you got bragging rights lol.

[andL64]

here u are super PI on 280 :D

:banana::banana::banana::banana: its also too large......

well i dont know if it gets fully stable but superPi does 280 on ur timings :D with max from tha booster 4.0-4.1 it showed but actually like 3,85V but until 270 i ran 3,5-3,6V real!

[andL64]

check my link kryptobs

[kryptobs2000]

Says the sites down for maintnance :(

I can't even give my ram above 3.7v with my 3.3v rail at 3.9v I don't know why. DFI reads it at only 3.8, so I can't even try it any higher, or make my 3.3v rail any higher, and I don't wanna pay 50$ for a booster so dosn't look like I'm gonna be getting close to 280mhz anytime soon.

I think for 24/7 I'll be running those timings you had (with the 16x for bragging rights lol) at 260mhz with 3.6v it SHOULD be stable, I'm testing it now, but if it's just under stable at 265mhz I'd think it would be at 260mhz. And I get 4000mbps bandwidth which was my goal. What is wierd tho, is I havn't set my timings completely relaxed but even with 2.5-3-3-10-10-12 2t it dosn't increase my oc.

[andL64]

what a mess damn! i would like u see this! check it out later

youre just right instead it lowered my oc on 2,5 or it even wasnt stable at all at 270 :D
even more tight even better it goes and more stable... i also reached yesterday with 280 2-2-2-5 this max but 284+ isnt stable at all.....

i think ur really save if u put a fan over it @ 3,6V shouldnt get any damage.....

tried the 4.0/4.1V on the booster which is actually 3,8-3,85 and my kingston doesnt get warm in idle and benches etc... but if ya playing etc.... or for prime it would get hot :D

so the fan ll do it :) !

seEn

PS: site is already up again :D

[Zanr Zij]

here my BH-5 512MBx2 result need 3.8v not stable :(

[andL64]

tight up ur timings dude and u ll break 8k :D

is the k8n neo2 good for bh-5 and bh-5 sticks and does it work with the ddr booster?

seEn

PS: msi nforce4 also?!

[Zanr Zij]

tight up ur timings dude and u ll break 8k :D

I'll try. Thx... My TCCD do better than BH-5.... I using Aircool so can get higher :|

[G H Z]

ok nice but....

pics say more than words...

Did you notice he is talking about 2x512 not a single 256 stick?

Best my BH-5 do in 2x512 is 248mhz @ 3.56v on DFI250/3700

[andL64]

i dont want to critizize someone....

i would only say lets see my pics they said it all; i got the ram yesterday and i m still benchin them so....

and i saw his tight timings and tried it here on my sticks to and see whooOo :D

[HiJon89]

I did show pics lol, what d'you mean pics talk louder than words?
I think he was referring to his post, instead of talking about his results he would rather just post pics, I don't think it had anything to do with you.

[andL64]

thx for saying what i wasnt able for :D

yes i meant my pics and the scores :)

*sry* for my bad english !

[kryptobs2000]

It's fine, just a misunderstanding, and ur english is really good imo. I wish I could give mine 3.7 or 3.8 I'd love to beable to just bench at 270+ I got a 92mm tornado on them with 5v too so it's not loud lol, only fan I had lying around other than a dinky 60mm fan.

I wonder why I couldn't get past 240mhz before. After tweaking my timings, and I made them alot tighter oddly, I gained 20mhz+

On a side note, I fixed the problem with it restarting, I just reset the cmos and no more problems :confused: oh well... it works
