I whould say 3.6V safe for 24/7 w/ resonnable cooling....
And do you have the 250FSB wall?
I don't think there is a wall. 250 is 3.5ghz i think my max on stock air.
But I've heard that sometimes they even go to 270FSB.
I just hope I dont have that wall on mine.....
I didn't even know it's possible for ch-5 to do 250 at 2-2-2-5...
my XMS3200LL did do 240.
My CH-5 CANNOT do 2-2-2 timings. Even @ 2.9V it doesn't do 200 FSB.
Actually ivan with the newer batches of CH-5 Thats no longer true. Theres a couple screenshots of 2-2-2 at something like 230. It takes a lot of voltage though, something like 3.3 or more.
Edit, sorry didn't notice the my at the start of your sentence.
over 3.3v 1.6v for me and then they started doing something. ps holding me back now. can only go to 3.36v under load.
I have some noname CH5 :stick: :D (Ithink i have a 250fsb 1-1 wall :slapass:
It runs 3D01/03/Spi/Hexus @ 249fsb 1-1 5-2-2-2 (3.3v):slobber:
But @ 250fsb 1-1 5-2-2-2 i get HD corruption:mad:
Also does 283fsb @ 5/4 >5-2-2-2 (3.3v):toast:

you need more Vtt and or Vmem and maybe Vdd.
wow I need to get some of that ch5 ram thatll own bh5! mine isnt too bad, 220fsb at 2-2-3-11 at 3 volts(cant go lower, dont want to reverse the mod) I can do up to 3.25v on my nf7-s whats the odds of me getting some corsair value for 240+ fsb at 2-2-2-11 dual channel goodness?
it will never own BH-5. Didn't you know that BH-5 can do 290fsb+ at 2-2-2-5-9-16 and 3.5-3.7V? :stick:Quote:
wow I need to get some of that ch5 ram thatll own bh5!
stestan: The wall is that it CANT pass 250FSB not MHz. ex: Like that they cant do 250FSB at 185MHz....
But my CH5 are new and can do AT LEAST 236MHz, 2-2-2-6, 3.2V
But I dunno about the wall(CPU was maxed out). Now I have my 2.4C M0 and vid card so I can test it in 2-3 days....
skate, the 250 FSB "wall" is only on intel systems ;)
But stestan is an Intel:p:
but Illicit Tweakin isnt :D :)
I think theyres no XP CH5 wall coze they cant go up to 250FSB:D
Here is my Ch-5
It was bought in early 2003, think the date is 0309.
This is at 3.2v and in my dfi.
I do seem to have a 250 wall.
i dont think all BH-5 will. my Corsair has a hard time staying at 260 with 3.6v.Quote:

that stick of 3200LL CH-5 i had seemed to perform almost the same as the 3500C2 BH-5 stuff i got now. both take about 2.8/9v to get to 220 tight, 3.1v for 230 and 3.3v for 240. i didnt have any Vmods with the CH-5 though. it may have done 250 with some more volts.
Mine are 03/11. And I think the CH5's can pass the wall w/ alot of volts....
ive seen people run 3.6-3.75 on these forumsQuote:

dunno if thye use active cooling lol
freind of mine had them running pretty nice on 3.4v, and then woke up one day....DEAD. CH-5 cannot handle voltage as well as BH-5. just remember that and be careful unless you could care less ;)
I am now just haven't changed sigQuote:

I didn't try further...
I now have a locked Barton that won't "even" do 11.5x240 ;) lol
I hit the wall with the cpu @ 11.5x229 :(
Anyway, now running the memory 24/7 @ 3.3v :) no problems whatsoever :)
here my OCZ PC3200 Platinum with CH5 on my K8V.... ;)

;)
290fsb is a record for bh5, far from average. and I neither have higher than 3.25 nor will I run it higher, not everyone has money to replace dead ram and I game besides bench so for 24/7 use, I want 3v max. bh5 may pull ahead at very high volts but ch5 can hold its own at less volts and thats what matters to most
...and these are two other CH5 sticks on an IC7-MAX3 @3.2v
http://www.burnerman.com/mems/ocz3500/ocz250ch5.jpg
byez :cool:
290 fsb isn't the record. I've seen some screens at 310, but I also doubt that many will do 290. Maybe in single channel. Either way the new ch-5 is a deffinate improvement. I'll still take the bh-5 though and I don't mind running mine at 3.5v. I worry about burning up other things with my 3.3v rail more than my ram, but then no risk, no gain.
bh5 ram doesnt seem to get along very well all the time on nf2 mobos, thats what I hear. Ive always had great luck with corsair value ram though. hows the price on bh5 and good ch5 currently
BH-5 will do fine on NF2 boards, it just takes some time to get it burned in and up to the task.
Witness charlie's ABIT nf7 @ 250 posted in these forums, Lastviking's DFI LP/Infinity clocks.
You can't slam BH-5 to high FSB in nf2 boards, you have to coax it.
For a pair of 256mb it looks like its about $40 more for the bh-5 at zipzoomfly, but it depends on where you get it from. I just got a pair of 256mb bh-5 for $120 which is $30 cheaper than what zzf sells hyperX pc3500 for.
the thing is, I had mushkin bh5 that seems to have started at 245fsb, such shame my published score at 245fsb was at 5x cause I was testing my ram. now I cant get 3dmark to complete past 220fsb. also prices of bh5 have gone way up too. I can get a 9800 pro for less than bh5 ram and games will run better too over my ti4200 and bh5. maybe once people all move on to ddr2, bh5 will be dirt cheap and I can try my luck again before upgrading to a64
The fact is CH-5 at 2-2-2-5 is slightly slower than BH-5 at the same settings.Quote:

Could be because they are 130nm parts where BH-5 is a 150nm part.Quote:

Its some really good ram, very nice scores.
How do we know which are "old" and "new" CH-5 ?:confused:
Theres a date on the chips its just written in a 'code'

IDD.... winbond rates both parts at 3.6 max. probably his PCB died on him or some resistor ect.... Daos, what brand was his ram?
I remeber when many of the 865/875 boards had a lot of trouble with ch-5. Many just wouldn't do anyting at 5/4. Glad to see that's resolved. They must have changed something in the pcb. Good news for the people with Intel rigs.
I don't think thats resolved, I still haven't seen people running CH-5 at high FSB 5:4.
I will say you that in one week OR tommorow(if i have the time). Mine are one of the last batchs made(11/03), and they can do 2-2-2-6, so if mine can go to 300FSB 5:4(w/ up to 3.7V) CH5 can pas that wall...
Do you have a link to the specs? 3.6v max seems crazy, since the standard is 2.5v....Quote:

i cant be bothered :p:
its on winbonds site in a pdf i think. 3.6 is listed as the maximum blah blah blah..... normal is 2.5 :)

Cant wait for your results m8. its gonna be a great contribution :toast: :)
So you guys think it's worth getting CH-5 these days with these new speeds being reached on supposedly better made chips?
What brand would be best, corsair value or what?
(wondering since I dunno if for sure to get khx3000:( )
OCZ 3200's, Corsair 3200's, HyperX 3500's would all be good choices.
should I go out and buy a few sticks of corsair value before they are all out? is 512mb or 256mb better chance? my 512mb is good but not great. 220fsb at 2-2-3-11 but ill be most happy starting at 230 2-2-2-11 dual channel baby

How do you read its made in 11/03 ?:confused:
and what batches are considered new?
Actually BH5 is 0.185.. not 0.15 ;)Quote:

Some rumors said CH5 lacked some pipelines for running tRCD 2 properly. Im no ram-guru, so for all i know it might be true!?
Examining the Datasheet for BH-5 and CH-5 there is no architectural differences.
The move to die shrink is the difference, and what ever "magical" layout/materials arrangement that led to BH-5 being so good is:
A) Unknown to the Winbond engineers so they cant even reproduce it...
B) Lost for all time....FK ME.
In otherwords, even Winbond doesn't know WHY the BH-5's were so awesome, and based on demand for high performance DDR, would make more in a heartbeat.... IF they knew how.
Just got a stick of Corsair 512MB PC3200.
I bought it from a guy, believing that it was rev. 1.1.
Opened the package and crap, rev. 1.2. Damn'.
The stick was going in my son's PC anyway, so i gave it a shot on my P4C800-E, knowing that I had some problems with CH5 sticks in the past. But that was on my IC7-G. Don't know if that affects the ASUS too.
Believe it or not, but I had no problems booting at 265FSB with 5:4 divider, 2-3-2-6 timings. Ran some 3Dmarks to check it, with no probs.
Of course, this was with only 1 stick, so maybe it might be different than when using 2 sticks.
Took the HS off, and it was CH5 indeed.
W942508CH-5
0350WI
Will try it later on my IC7-G and see if it works on that one too.
W942508CH-5
0346WI
Almost the same...
Did you try higher FSB? some have the wall at 270.... And have you tryed 2-2-2-6 w/ alot of volts?
Nope, not yet.
Just plugged it in my IC7-G at 260FSB with 5:4, 2-3-2-6. Booted nicely.
Will give it 3.2V and try tighter timings.
:eek:
i wal usually comes at around 255-260 fsb. i had it at 259 lol. try going to 270 5:4 and if u can post, then the wall is gone!! :slobber:
Here's 270FSb, 5:4, 2-5-2-2, 3.2V :
Haven't test it on stability.
Same settings, quick 3DMark run :
IC7-G, aircooled
Very nice, my CH-5 could NOT do that...
Black hole from 258-up.
Thx.
I'm quite surprised myself.
I guess that the memory chips are getting better or so, don't know. My board is the IC7-G, which I bought in july last year, so pretty old. :D
I sure know that they a lot of voltage to run at this speed.
To bad I can't test it with 2 sticks, I only have 1 :(
I presume thats a 2003 week 50.Quote:

So what's a general guide for "newer" CH-5 that has no divider problems (fsb wall) and can do T ras to cas of 2 at high volts? from which week onwards?
By the way, I have a pair of CH-5 which has this second line:
03275I
How on earth do I know what week that was produced in?:confused: (My guess is its an "old" CH-5)
I think that your's are week 27.
Things are looking up for ch-5. It would be nice to see if they could do this in dual channel
You're right.
I should have bought 2 sticks of those. The guy I bought it from had 2 sticks. I bought one directly but forgot the other auction.
And who knows what kind of sticks you get now, which week they're produced and stuff. I might go and try to buy another stick of PC3200, and see what it does. Can always sell it afterwards.
To bad, but to compensate, I found a nice stick of 512MB PC3500 Corsair for 95€. :)
Damn, hard to beat a deal like that. I'm not that familar with Corsair, what chips does that have?
BH5, like all PC3500 from Corsair.
PC3200 rev. 1.1 = BH6
PC3200 rev. 1.2 = CH5
PC3200LL rev. 1.1 = BH5
PC3200LL rev. 1.2 = CH5
PC3500 rev. 1.1 = BH5 (there's only 1 revision of this kind)
Very nice, great bargain you got there. I need to find two of those.
hmm so for CH-5 there're 2 kinds of markings...
03XXWI and 03XX5I
can that mean anything?
or should we just look at the week (XX) to identify "newer" CH-5?:p:
If that's true then I think Winbond got some serious problems in their development lines..good products should be inked out so that one may continue to profit on their excellency..so what I mean is dam, wish they would start making new so prices would drop and we could all get some of these awesome sticks for cheap $$$$..Quote:

I made a post with timings on page 1:banana:
I think the issue is, they upgraded thier fab to make .13um chips on bigger wafers with a HUGE increase in profitability...but... that meant replacing all the machinery. So going back isnt just pulling the films out of storage, they would need to reconstruct the old fab, who knows what happened to the old equipment. Companies rarely keep that stuff around, they sell it off.
But, maybe there is gold in the CH-5's, just noone has made a memory circuit/northbridge to best utilize the CH-5's yet.
Any updates on how the CH5 sticks do in the IC7-G?
hey, it's nice to see some other lucky people that got some good ch-5. Mine does 240 at 2-2-2-5 in an IC7 Max3 with 3.2V. One more mhz, and it errors in memtest. And about that 250FSB wall, i see it at anything over 250 with the 5:4 divider. Oh well, 240 1:1 isn't that bad. Oh, they're Corsair TwinX 512mb sticks running dual channel.
Nice! I've got 2x 256mb sticks of Corsair PC3200LL CH5 coming, and wasn't sure if it'll run in my IC7-G, but yours seem to run fine, even with dividers.Quote:

I assume that 300FSB 5:4 = 240Mhz ram with 2-2-2-5 timings isn't a problem with PAT enabled?
I have seen verry few CH-5 doing those timings / speeds in dual channel
for a while, thought they might be bh-5 or bh-6, until i popped the heatspreaders off and they said ch-5. i was suprised to say the least. But, no, they don't work well in the 5:4 divider. won't go over 250fsb no matter what the voltage or timings.
haha BH-5 was a mistake that was a success...what an oxymoron:DQuote:

Does the CH-5 get a boost mhz wise if you push the volts like BH chips does? Couse I have had my board stable at 230 before and now with my new CH-5 that does 219 11-2-3-2 with 2.8v it wont be stable at 220 with upto 3v! My question is if I up the voltage, will there be any mhz boost so that I might be able to do 230 with say 3.1-3.2v? The mems are CL2 rated KHX PC3500.
yea.. on my abit nf7-s rev2.0 week 0308 i have a set of 2x512 mush 3500 ch5 that owns my 2x512 khx3200 nona pretty hard.Quote:

this stinking khx :banana: :banana: :banana: :banana:s won't run on this nf7s, i can barely run 200-6-2-2-2 with it at 3.06v (11-2-2-2 works as well). anything above and prime (lot'o mem test) tells me to shove it. my mush will do 220-11-2-2-2 at that voltages. runs 230-11-2-2-2 but starts screwing up then - needs more volts.
with the khx3200 i can run sandra up to 230-11-2-2-2 at 3.06v, but it won't run even 1 minute of prime with those settings. - i got 3 sticks of khx3200/512 - non of those will run on this nf7-s at anything beyond 200. i got a single stick of 3200/256 khx that'll do pretty good.. and 2 sticks of mush 3500 lvl2 bh5 that will go as far as 240 (sandra stable) with said voltage.
what about the rumour of mush ch5 having a voltage limit (fuse or stuff)? if it doesn't have one, i'll vdimm mod my board and see how far i can get them - at least the spreaders on all my ram has good contact.. they get quite warm :)
