View Full Version : Burning in some Twinmos PC3700
Hello guys,
Right now i'm burning in my brand new Twinmos PC3700 with Prime 95 @ 220x10,5 settings 11-3-2-2.0. :)
I'm shoving 3.0Volts up it's ass.
How much can this RAM handle?
For my Twinmos/Winbond BH-5 i wasn't scared to give it 3.23V but for this RAM i don't know yet.
Is this the right way to burn in RAM? :confused:

im running my twinmos 3700@245 2-2-3-11 with 3.3v for some weeks now :)
i get a prime error after 6 hours, but i think its the chipset, not the memory.

i have to do the vdimm mode
how can i burn a ram with max 2.85 volts :D

What's the benefit of 11
11 seems to give the best performance on Nforce based mobo's, if you're a regular on this forum (which i presume u are) you ought to know this... ;)
The RAM actually appears to be mighty good, something else keeps holding me back.
Strange that RAS to CAS delay needs to be set at 3 for this RAM, setting it to 2 results in a no post. :confused:
I'm sick and tired of trying to find out what's holding me back, will make do with the OC i know is safe for a while. :(

Yep, it's a must..... @Trcd = 2 you'll be able to run like 180-190MHz at most.... but @3...... well, that's a different story ;)

Oh yeah i'm under the impression this RAM is capable of doing some nice stuff, wish i knew what holds me back....
Just FYI - that 4.3ns TwinMOS doesn't like high Voltage very much.... mine won't run @3.1V or 3.2V.. not sure about 3.3V+, that's too high for me.... :)

Well thanks, i've read that before somewhere.
I had it running at 3.1V tonight but was §§§§ting my pants, only got it this afternoon. :D
Saaya on the other hand claims to run it at 3.3V for 3 weeks now.
Hope to get more out of it soon as i find out what's holding me back. ;)

Nice theory, but real life testing shows that 11 is best for Nforce based mobo's. ;)

On the mainboard level, the KT400 has reinstated the dark ages of sloppyness with respect to BIOS settings that are listed as opposed to what is really supported by the chipset. One of the key issues that is seen over and over again is the listings of tRCD and tRP values of 3T in DDR 400 mode. Plain and simply, the chipset does not support these latencies meaning that in DDR400 mode the only valid values are 2T and 4T. Unfortunately, the mislabeling is also being exploited by memory vendors that are using the fake BIOS settings to claim lower latencies for their modules, that is 2:3:3 latencies in DDR400 mode.
GRR!1!!!

Truth be known I'm not even running a nVidia chipset based system at the moment. "...if you're a regular on this forum (which i presume u are) you ought to know this." I only happened along on this thread because it mentioned a memory which SPD is more condusive to Intel chipset attributes.
And now for my "real life" theory. I merely referenced that to try to help, in leading you to a BIOS guide for general source material. There are many memories, ANY memories which one would want to use in conjunction with the nVidia chipset, over Twinmoss PC3700. The answer to your problem lay in the title of your post. At the risk of being redundant; "...if you're a regular on this forum (which i presume u are) you ought to know this..." ;)

thats not true dude, maybe your board couldnt supply it with a stable voltage so thats why it wouldnt run over 3.1v
my 3700 is running with 3.3v for weeks now, it even runs with 3.6v but it doesnt get any faster.
nice avatar liquid :D

It's kinda bothering ya, isn't it? :)
I thought it was common knowledge to anyone visiting this forum on regular basis wich i knew you do.
Anyways, i don't really see why i would want any other RAM over this Twinmos PC3700, seeing i came from Twinmos BH-5...
The only disadvantage i can see is that it needs RAS to CAS delay set to 3, if that's an disadvantage.
What RAM would you, as a regular to this forum :D, recommand for a nVidia based mobo?

What RAM would you, as a regular to this forum :D, recommand for a nVidia based mobo? I thought I already apologized for my asinine remarks. I guess being as there's BH-5 in the Twinmoss 3700, then that be fine. I should have known that. I've been very confused as to why these IC's are running so well on both Canterwood/Springdale, nVidia, VIA, and just about everyother chipset on the planet.
I was going to suggest Corsair Twin-X3200LL or Corsair XMS3500 (which apparantly has the same IC's as the 3200LL) i think their all BH-5. Although I'm not gretting great results wiht mine, perhaps due to the anemic voltage of the Abit IS7-E. I'm thinking about taking out my Soltec SL75FRN2-L (adjustable VDD to 1.8V) and thowing in my JIUHB1700, because I have Twin-X3200LL. I'm sorry everything is crashing down around me, and it's frustrating when you have memory like Corsair Twin-X4000, and then people come along with Twinmoss PC3700, and wipe the floor with ys benchmark wise. Si I'd presummed the memory better suited for Intel chipsets. This is because memories like OCZ EL-PC3700 run terribly on an Intel based chipsets. So I'd attributed your troubles to this. And there I was being sarcastic, towards you thinking you were sacarstic towards me. Which is fine, until soemone else does it? :confused:
Not running a nForce based mobo currently I'm out of touch with the better memories for it. I was however promised a water-cooled LAN-box from a Manufacturer, and then they simply broke their promise. I even have the email where the guy says "your system was shipped per your specs except the system was changed to AMD..." a week later nothing arrives? They even promised to set up a domain for a sight, and blah, blah, blah. Have to be careful for the "used car salemen" who take advantage of our passion. ANyhoo, I was miffed over that, and displaced my frustration on you, sorry.
No hard feelings man!!!:D
I found all the ppl over here to be Xtremly relaxed, that's why i stuck around for a while.
On the Twinmos PC 3700, i have to say it runs fantastic in this NF7 mobo but my good old Twinmos/winbond BH-5 outperformes it by a small margin just because it allows me to run 11-2-2-2.0 instead of 11-3-2-2.0 for the Twinmos PC3700.
On the other hand, the 3700 only needs 3V to do 242, the BH-5 gets 3.23V shoved up it's ass.
Again, if 've been a little rude, i didn't mean to, please understand that i'm dutch and might express myself a bit wrong because english ain't my native langue. ;)

No it isn't this new twister stuff, it's just the old twinmos/twinmos 4.3ns pc 3700 cl2.5.

Ok thanks!
Do you know anything about the new twister ram is it any good?

I'm sorry, i have no idea, but going from the quality of the PC3700 and PC3200 i have i presume it must be good. :)

I've Twister PC3700 runing them 223MHz @ 2.6V. I'am having some problems with NB... So I'll have to do some Volt mods and probably watercooling of NB...
Twister runs up to 240MHz 2.0-2-3-6 @ 2.9V. And up to 260MHz 2.5-3-3-8 @ 2.9V
Quite good for their price.

10-01-2003, 08:15 AM
then its about the same as the normal twinmos 3700 it seems, does it have tsop or wlcsp chipsß
TribesMan
10-01-2003, 11:22 AM
Twister is only available with wlcsp package.
They run extremely cool. After 8 hours of F@H 223MHz the heatspreader wasn't even warm. I like it.

with how many volts? my twinmos 3700 gets really warm with 3.3v, i ried 3.6v and burned my fingers! :D

3.6V!! :eek:
You are deliberately trying to hurt it, aren't you? :D
I was §§§§ting my pants just to give it 3.1V...
Did it take you any further?
I was under the impression that this RAM did as good with 2.9V as it did with 3.1V. :confused:

going from 3v to 3.2v gave me ~10mhz more speed on both my twinmos 3700 and my khx 3500 (bh-5)
3.3v gave me ~3 more mhz and anything above 3.3v didnt help to get higher speeds at all.
heheh well i wanted 250dc with cl2 really bad so i raised the voltage more and more but it didnt help... so at 3.6v i thought ah well 245dc isnt too bad either :D
TribesMan
10-02-2003, 05:56 AM
There is no need to run Twister at such high voltages. They run just fine with voltages under 3V. Mine run 223MHz with 2.6V 100% stable and at about 24°C.

10-02-2003, 06:08 AM
well if you only want 220 fsb ;)
TribesMan
10-02-2003, 06:36 AM
I want 250MHz but there is a problem with my northbridge, and as I told you before I need to do Vdd mod and place waterblock on NB, some NB laping will have to be done also...
But in last 2 days I've been at home fore about 18 hours and if I sleep 8 hours per day and need about 1h for dinner there is no time to do mods like this. I'll make some mods thru the weekend.
Will report if some progress will be made.

what board do you have? i love the pcb design of this board, vdd and vdimm mod on my a7n8x took me 15min for each mod.
TribesMan
10-02-2003, 08:29 AM
I've NF7-S v2.0. Mod is no problem to me I'am an electrotechnic studend and I'am quite good with soldering iron.
You should see my BH6 with home made TurboPLL, fixed PCI/AGP frequency mod. Added CPU power supply MosFETs... And you should see this board running 184MHz FSB with celeron 700 @ 1930MHz @ 3.2V
Some fuc*ing action
There are the pictures, in case if you don't belive me.

cool! how long did you take to build the turbo pll?
what chipset voltages have you tried?
have you tried raising the rails?
how are you cooling the cpi?
what scores are you getting with that celeron in 2k1 and sandra?
btw, can you raise the agp speed to anything you want as well?
my 8500 loves high agp clocks but i cant set it higher than 100mhz on my board...
:D

Complete designing and building of TurboPLL took me about 1 month. But the majority of time was taken by designing it. It was built and tested in two days.
Chipset voltage on BX is taken directly from 3.3V so I raised 3.3V to 4V, RAM also ran at 4V
Rails were 3.3V@4V; 5V@6V; 12V@12V. But I used seperate power supply for HDD and vent's.
CPU was cooled with some cooper heasink. But the whole testing was made at winter and air temperature was -28°C, so CPU ran relatively cool (around 15°C).
Scores in 3Dmark2k1 was made only at 1800MHz but It wasn't posted because there was no modem or LAN card in PC at the time of testing. And the test was made with Riva TNT2 M64 so it is not worth mentioning.
You can see Sandra scores on first picture.
AGP freq was fixed at 80MHz. And I don't know what radeon you have but mine hates any frequencies above 85MHz.
And that board is dead now, because i shortcircuited the chip that regulates CPU voltage, while I was doing some aditional mods... bad luck.
My current setup:
Athlon 2000+ @ 2560 @ 2.05V
Water cooling
NF7-S Vdd@1.7V; Vmem@2.6V
223MHz FSB DC
R9100 @ 310/310MHz
3DMark is not tested yet on new RAM but before I got 12.5k 2k1marks, with SC memory @ 208MHz FSB.
So it should be around 13k at the moment.
Will test soon.

its a powercolor 8500 PRO 275/275 with 3.6ns hynix memory...
i set vid clocks to 300/300 permanently and then upped the agp clocks in 5mhz steps and rand 2k1 after i booted, here are the results (9x240dc 2-2-3-11)
11218 66
11277 70
11271 75
11294 80
11293 85
11284 90
11319 95
11286 97 (95 not available)
11300 100
as you can see 95 was the highest, but im not sure if it was just a nice run... i only ran 2k1 once...
