Twinmos pc3700 or Twinmos Pc3200?

[ColdFlare]

Hey i'm about to buy new ram, going for 2x256 sticks.

I'm going to try to get the most out of these ram, so I'm not really sure which one to get. The Twinmos pc3700 have twinmos chips, and the Twinmos pc3200 has winbond bh-5 chips. Which one would overclock better?

[XtremepH]

well i have the Twinmos PC3700 sticks but unforutanetly i can't go any higher than 212FSB @ 2-3-3-7 timings which is the limitation of my 8RGA+ mobo. I have also had some experience with Twinmos pc3200 winbond bh-5 chips that was good since they didn't overclock at all and i had to run it at stock and to run 2-2-2-5 timings I had to give it 2.9v for it to be stable. but overall th pc3200 ram have been very good overclocking chips i just wasn't lucky enough to get one. but if you know your mobo is capable of doing high fsb i would opt for the pc3700 stick since it is rated at 233mhz but it would then depends at what timings you might be able to get it to run at.

[TheDude]

I just got 2 sticks of 3200 DDR Twinmos/winbond 256 for $49 ea at memoryX, the price will go up to $54 very shortly.
I have not finished playing with the ram yet...currently only at 187fsb(tight) x 15= 2818mhz with my 1700+ cpu....but I bought this ram in an attempt to get 230+ fsb tight timings with my NF7-S mobo. My Kingston 3500 HyperX did 215fsb tight tops in this board. NB compatibility problem at high fsb.
I will post when I top out FSB...burning ram a little now before I go further.:D

Might be hard to find Winbond CH-5 stuff, but looks quality stuff

[TheDude]

Good article....thanks b|gf|sh :D

I tried looking around google for the ch-5 and I could only find one site that carried it. They are asking for 100 bux for 256meg stick with ch-5 chips, thats highway robbery.

Man I still can't make a decision, I've heard the pc3700 twinmos with twinmos chips are good for intel, but I'm running an AMD rig, should I go for the twinmos bh-5?

Edit* I've also found some twinmos labled pc3700 with winbond.

[antipop]

The pc3700 uses twinmos chips and not winbond, i'd say go with the 3200

[Xizten]

My Twinmos Winbond BH-5 dows atleast 440 mhz 2-2-2-6, my BN stops me from going futher.

will do a vdd mod quite soon, shall be fun to see were this $50 memchips max out

[TheDude]

I have to drop the multi to get any higher fsb....I think my chip is maxed out at 194x15=2912.85
Might raise it and go lower fsb to see if get higher clock:D

ColdFlare,

Where? Could you post a link for me?
Thanks :D

TheDude,

Whats the link to MemoryX? I am looking for some TwinMos 512mb sticks of 3200.

Thanks

Adam

[Adam Harvey]

Thanks. I am going to have to buy some. This 512mb stick of TwinMos 3200 for $90 looks awesome.

That's true...thanks...I didn't notice he posted .com
Good eye ;)

[Craig]

I'd be interested in anywhere that has the PC3700 with Winbond chips.

And has anyone seen any RAM with the new CH-5 chips yet?

Links for the above?


Thanks

ColdFlare sent me a link to someone on a forum selling Buffalo brand 3700 with winbond, but now I can't find it. Do you still have it ColdFlare? I have heard that Buffalo is good brand, but have not tried any yet. :D
I have not run across CH-5 myself, but remember seeing posts in this forum that some have. Still kinda new...memoryx didn't have it yet when I talked to them a couple of days ago.

[ColdFlare]

Buffalo pc3700 Buffalo (http://www.amdforums.com/showthread.php?s=&threadid=215882)

I've not had any experience with this guy, but he seems pretty popular at amdmb.com.

I've also found ch-5 memory for 100 bucks a pop for 256meg which is highway robbery. If you guys want to look at it, I can try to find the link again.

OMG CH-5 For Cheap (http://www.hardcorecooling.us/product.asp?0=200&1=201&3=407)

Here is the link to 512 meg, not 256, I repeat 512!!! ch-5 Winbond, Other details unknown. I've found the link for you guys, cause you guys are xtreme, and xtremesystems runs on love.

Manufacturer of the memory is unknown but they do use ch-5 chips apparently, so buy at your own risk.

Here is their Resellerratings

Ratings (http://www.resellerratings.com/seller1698.html)

Their not that good, but decent.

I am in no way affiliated with this company because i'm currently unemployed.

Anyways Have Fun

[TheDude]

Thanks for taking the time to post that ColdFlare:D

[Adam Harvey]

TheDude did you look at the CH-5 chips? Would that be a good deal to do.

Adam,

I haven't seen any yet. I got the BH-5...just ordered heat spreaders today.:D

[Adam Harvey]

I just want to be like everyone else and ask why you got heatspreaders, they are needed. Sorry I had to do it, I was joking around. I love the heat spreaders on my Mushkin. So the BH-5 chips still get to like 210+ whats the highest those get up too?

:slobber:

[TheDude]

Adam,

I don't know yet, haven't been feeling well last few days, but will try to push them this weekend and let you know. I had them to 205fsb for far. My NF7-S doesn't seem to want to give me too high FSB with any ram.
I will be putting together an Epox GA+ this weekend also.

[Adam Harvey]

Ok thanks. Been learning a lot about ram and the 1700's over the past 2 days. Over 40 post. Not as many as some people but sweet.

Adam

[TheDude]

Excellent....good to have you here, Adam. :D

[sjohnson]

Others have done better, but TwinMOS bh-5 are good to at least 226 ;) kd7-e, tbred 1700+ JIUHB on this bench.

[Adam Harvey]

Did you do anything special to make the ram go to 226? Burn it etc.

Adam

[BrainStorm]

That's some nice looking bandwidth, Mr. Johnson...:)

[sjohnson]

Sure, did a lot of burnin: memtest, prime, sandra, f@h, 3dmark loops, gaming, posting on this forum (hey! try it, it works ;) ).

The stick was stubborn at first but xtreme members posted about how good it got after a long burnin so instead of RMA'ing it I kept after the stick. Try a search on "TwinMOS" and you'll find more than a few threads. My score is low (but nice efficiency for a AMD rig) compared to some in those threads.

It thrives on volts and just feels like it shakes off abuse.

BrainStorm, TY! nothing anyone here couldn't do with some time and patience, though...

(Edit) Take a look at Bowman's bench in http://www.xtremesystems.org/forums/showthread.php?s=&threadid=12054&highlight=twinmos - or better yet, Henry's ;)

[Bravo]

Just wanted to post to fill an information void.

Chainbolt, a regular on the OCAU forums, supplied me with 3x 512mb TwinMOS PC-3200 sticks. Of the 3, two were CH-5 module sticks capable of 220mhz @ 2-2-2-5 @ 2.9v (1.7 Vdd) on my NF7-S 1.2, the other one was a BH-5 module capable of 210 at the same voltage and timings above.

This was supplied without any burn in. I am currently running all three sticks at 200mhz @ 2-2-2-5 @ 2.9v.

Definitely the CH-5 module sticks are a good 10 - 12mhz faster then BH-5 module sticks straight out of the packaging :)

[#ball3r]

I just got my 2x256 twinmos 3200 BH-5 from Scott Cross on the amdmb.com forums and this stuff is the sh*t ;). I swapped it right in to my abit nf7-s 2.0 that was running 2x256 ocz 3500 dc at 225fsb 2,2,3,3 and it ran perfect right out of the bag. Right now I'm running 228 2,2,2,3 dc sync and passed about 20mins of memtest test #5. I would've tested more but didn't have the time, no errors though at all. So maybe when they get burned in a little they will go over 230 no problem. By the way it is with 11 multi on my 1700+.

sjohnson, what did it start out at? Also, what voltage did you burn-in at?

Adam,

I don't really think spreaders are "needed" as far as increasing fsb or even reducing heat to be honest, I got them because I don't like to handle Dimms by the chips and they look cool. :D
Right now, I'm at 225 fsb and 2v. By end of weekend, I hope to have higher fsb and lower volts. ;)

[sjohnson]

Both sticks I've bought started out at 170/2.5/CL2-2-6-2-1t. No higher. Almost RMA'd them when the posts began here showing great B/W after burnin.

It took about a week to get them to 200/2.9/CL2-2-6-2-1t.

I can take either to about 208 at CL2, after that I need CL2.5. 3dmark01 does get better scores with CL2.

Just before I finally landed a job, I'd taken the sticks to 226/3.15/2.5-2-6-2-1t.

Two points - 1. my kd7-e undervolts both CPU and memory. That 3.15 Vdimm was showing up as 3.04 in MBM (TTGI 520 watt tweaked PSU).

2. Both CPU-Z and Sandra report my BIOS Tras 6 to be Tras 5. They also show BIOS Tras 7 to be Tras 6. The system "feels" like that is true, as well, I'm getting 97% Sandra Float efficiency at CL2.5. So, I can't prove it but the memory would seem to be running at my current max, actually 226/3.04/CL2.5-2-5-2-1t. Pretty nice timings if so...

I *really LIKE* the TwinMOS BH5, getting ready to buy some CH5 to compare :D

(Edit) Burnin started at 2.5 - I kept working it in with lengthy burnin sessions until it felt topped out, then bumped the volts. Nice and slow. I've never had much luck slamming memory, though that's the only way I get good CPU clocks. If I try to go slow and gentle with a CPU I always end up with a weak one. Go figure!

[BrainStorm]

So don't slam the ram, but screw the CPU? :D

Thanks for the input!

[sjohnson]

rofl! :D

[TheDude]

sjohnson,

I'm at 225/2.9/5...2...2..2..cas2 vcore set at 2.1 DDR at 2.9 chip at 1.7 agp at1.5

I tried for weeks to creep up on it slowly and always topped out around 205 to 210 fsb....finally just got pissed and tried all max at 250fsbx11 and got siren...then dropped down to present settings and got into windows steady as a rock. Almost afraid to touch it now. But you know I will :D

[JeffPH]

i use to have a PC3200 Twinmos TMD chip on my 4pea+. i was able to runit a 180 FSB no probs with all the benches and Prime 24/7. setting were lax tho 2.5-7-3-3

[Craig]

Thanks for the links guys.

[Craig]

That link at hardcorecooling now shows those sticks for $96.87 to be cas2 512mg. sticks.

Would seem like a pretty good deal.

[sjohnson]

TheDude, got me beat anyway, I can't run CL2 above 208, have to drop to CL2.5. It's 3dmark01 stable to 224, not loop stable but bench stable. I'm getting pretty poor 3dmark01 scores above 218 FSB. Plus, my d-Link NIC cuts out above 210FSB. If I use setfsb to drop the FSB after a 3dmark run (to get the NIC to work) it won't let me publish.

I'm not a bencher as much as a gamer so I don't run mine regular above 208, not until I find a NIC that won't cr*p out.

[TheDude]

I'm not a bencher either, but love games. I ran 3D 2001 and got about 16400. Timings all tight at 225 fsb. I'm sure it would do better if I knew what I was doing. My 9700 mods are not on. The thing is finding the highest multi that will still allow 225fsb with tight memory. The chip will do 2.9+....but not at high fsb.

[sjohnson]

heh, about 14600 here on my ti4200. Can't crack 15k, don't know what I'm doing either.
