utt ch-5 without dots?

**Gipse** · 06-30-2005, 04:51 AM

hi,
this is my first post here, so please give me some time.
I bought a kit of 2x512 from COMPUTERSMSA (they should be winbond ch-5 utt). Ram arrived today and I was very surprised when looking at the chips, I canÂ´t find the typical "big dots"

So are there any uttÂ´s from winbond without dots?
Ram is currently running on my dfi lanparty ultra b @ 10x240 (cpu could do up to 10x255) with 2-3-2-5 2T timings @ 3.2v (they get warm, but not really hot), few errors in memtest.
Hope to find help here.
Thanks

they REALLY arent there??
Because sometimes you can barely see the dots on the chips.

Are there 2 metal bumps at the sides of the chips?

hi,
hereÂ´s a pic:

mine looks the same, no dots as you can see...
he wrote back:
"The factory have only Winbond chip â€¦

For you, which chip can 2-2-2-5 @ 3.4V @ 250 MHz ? Only UTT Winbond CH-5 or BH-5, or few Micron chip.

- Micron is more than 3x expensive per chip.

- UTT BH-5 is about 2x expensive per chip.

Is a UTT CH-5 0.13Âµm chip, you can trust me."

I really donÂ´t think that he want to sell "cheep" and faked ram to me!
So what do you think about it?
Thanks

Should be try 2-2-2-x with 2.8-3.1 V dimm first. If it boot , its CH5-UTT

**Gipse** · 06-30-2005, 05:57 AM

boot was fine with these timings and voltages.
never seen ch-5 utt without dots, do you?

The dot in the lower left corner is not like the one in all the other XH-UTT ICs.
The metal slabs in both ends seem to be closer to each other than usually... (?)

Could it be CH-UTT but made by, say, like Infineon?

Or Winbond has done something to their ICs.

**alphaalien** · 06-30-2005, 10:47 AM

There were some Winbond CH that don't have 2-dots, but all recent production from Winbond, within the last 3 months, have 2 dots. Prevoius to March there were CH available without 2 dots.

**Gipse** · 06-30-2005, 11:46 AM

is there any difference in production?
like others voltages or something else or is it just a visiable "issue"?
currently IÂ´m running a burn in @ 200 2-2-2-2-5 @ 3.2v (for 10h now); will flash another bios (last from tictac is optimized, will try hellfireÂ´s rev.2 bios) and run a burn in @ 3.3v with 240mhz.
will report results here

just to make it clear: I donÂ´t think/claim that computersmsa sell bad modules

This might be some cheap Samsung or Micron IC but it is not Winbond-this is my opinion.I can't see two metal stripes over side of IC-there is four small metal dots(as i see your pic) which means is not Winbond

**Gipse** · 06-30-2005, 11:56 AM

so what do do

I bought it via ebay, is it allowed to share the link?
computersmsa promised me that these chips are winbond utt ch-5; but how can I identify the manufacturer.
I payed for winbond and I want to get winbond chips. So please help me.

Ive read many posts about this computermsma and I have not read ANY complain but very good overclocks, so iÂ´d try that ram out first before complaining.

**Gipse** · 06-30-2005, 12:17 PM

to make it clear for the third time, thread is not related to complain about the delivered ram

I was just wondering about the missing dots, thats all. hope you can undestand me. as I mentioned iÂ´ll report results after finishing my first burn in and flashing to another bios.
so give me 20min. and I can giver additional information.

now thats what im talking about

"dfi lanparty ultra b @ 10x240 (cpu could do up to 10x255) with 2-3-2-5 2T timings @ 3.2v "

sounds like utt to me

**SDX** · 06-30-2005, 01:00 PM

They look like the IC's on my Value VX:

**Gipse** · 06-30-2005, 01:12 PM

first results from memtest after first burn-in session.
currently running 2T 10x245 @ 2-2-2-2-11 @ 3.3v (bios). memtest #5
pass 1 and 2 no errors, following every pass 1 error
bios is hellfireÂ´s rev.2, alpha timings not touched.
seems to be utt

what to do now? I know itÂ´s a little bit old-school oc, but as a student you are limited.
Thanks foryour help.

Set CAS to 3. If it boots, it's not BH-5. If it does, try SuperPi 8M, or MemTestx86+. If that fails, it is probably BH-5. My old school BH-5 boots into Windows fine at CAS 3, but when I login, it reboots (or sometimes it just freezes).

EDIT: Oops, thought you were talking about BH-5.

**uscfan** · 06-30-2005, 01:19 PM

Feed it more volts and if you can do 250 at 2-2-2-5 then it has to be windbond.

**Gipse** · 06-30-2005, 01:25 PM

3.3v (bios) is all I can give

I know there is a vdimm-mod but I donÂ´t want to

my mobo
any other ideas?

edit: northbridge @ 1.8v, should I give 1.9v to eliminate errors?

Hi,

I have received UTT BH-5 in first, and I have see two dots ..as typical Winbond chips.
The day after, I have reiceved the UTT CH-5, without two dots ... I have been suprised as you ! But for sure I have order UTT CH-5 0.13Âµm chip ... and factory order it at Winbond, finally for 99% sure it's UTT CH-5 0.13Âµm chip.

Some people make 250+ MHz 1.5-2-2-5 or 2-2-2-5 @ 3.4-3.5V ... only Winbond can.

Have a nice day/night

Edit : I will answer the factory tomorow (Sales Manager can't help me maybe, wait engineering)

My UTT BH-5 not boot at CAS3 and can 2-2-2-5 @ 200 MHz @ 2.6-2.8v
My UTT CH-5 can boot at CAS3 and can 2-2-2-5 @ 200 MHz but need 2.9V-3.1V.
