Some Old Skool Twinmos Bh-5 Goodness......

[s7e9h3n]

I'm so amazed at what these puppies are capable of that I had to start a thread here to show them off This is a 2x512mb set with original Winbond 312WE BH5 IC's. This was done all on air with the FX55 from my sig:

First the sticks:


Now here are some Spi Runs:




And check out the timings on the sticks for this 32m run



I'll try for higher later, but they've basically done whatever I've asked of them to this point........

wow very nice sir

[Onepagebook]

looks like you learned mcuh as you can huh

But these TRRD/TRAS really helps to increase mem freq or stability?

Neither....it helps give better times

I'm just jealous That's a steal indeed, Steven
Fast n' tight

Funny thing was that these sticks wouldn't take the 3.7Vdimm until I popped them in a couple days ago. Before then, they'd get flakey @ 3.66+V. I'm still trying to figure out what I have set different, but I'm pretty sure I've made no changes since when I first tried these sticks out....

Very nice clocks for 2x512mb 'old' bh-5!

[5days]

I'm getting some old school Corsair BH5 soon. 2x256 though.

Do you mind if I ask what Chipset you used? (Motherboard?)

Great Twinmos!

They do ~ the same, as my Mushkins.

Nice clocking man
Real nice memory too...

[s7e9h3n]

How safe is it to use the 5v jumper on the DFI ? I read somewhere that it kills ram , is this true or was it a rumor?

The key is to use as high as a vdimm as possible No joke - the less the difference between the Vram and the output of the 5V rail, the less votage the IC which regulates your Vram has to displace........And besides, those rumors only hold true for UTT. Old BH5 sticks are built like tanks ..........

Thx man, this one's right up your alley ;
I was messing around yesterday with the memory @ 270 and ran 3dMark01 to see how big of an improvement LL ram makes on scores. Now I don't run 3dMark much at all, but I thought that this score was pretty good considering the cpu's on air and the vc is only @ 594/614. No tweaks at all (besides what can be done with the stock drivers)...

[funkflix]

The best programm to check the difference between different ram-timings, is Pifast, it gives u a way better steady results than SuperPI! And it reacts spontaneous for every little performance increase.

Just a few tests, and u can see, that all reserved values have no influence for the results. But, as an example, Idle Cicle Limit from 16 to 0 gives u a good improvment.

As u can see, all the reserved values, not supported by IMC of A64, gives u no improvment, it's just an optical gimmick, nothing more and nothing less!

Edit: The fastest timings my DFI/IMC/BH5 can handle without an reboot, after Bios-screen.

Hmmm....thx for the screens....I'll have to try running that later. Just curious though - what cooling are you using? Cuz ~25C cpu is definately not easy to do on air.
This RAM hasn't hit it's limit yet as I'm actually running into heat probs due to the vcore it requires to run @ 270+ x 11. Well, that won't be in issue once I throw this setup back under the autocascade this week

[funkflix]

It's water and A64 without IHS.

[funkflix]

My PC3500C2 did 270+ on Neo2, with Vio = Vdimm Mod! Have u played with timings on A64Tweaker? Bios is really pure, try the 1.36b.

[TheMeatFrog]

Very nice old school bh5 s7e9h3n! Since my VX died and I can't RMA them because they're naked I'm currently in the market for some myself.

[Onepagebook]

try this, looks easy huh,

[funkflix]

Hmm, crazy timings! I can't boot with Trfc 11 nor with Trrd 0, maybe i should try other Tref.

[funkflix]

No go with Trfc of 11, not even with 3,8V.. OPB, what kind of rams did u used for this run?

[Onepagebook]

That one not even crazy yet.

this 32m can be done @ 3.17(actually 3.13v under bios)v is a bit crazy

Took from Digi-cam during middle of running.:




finished.


Windows screen



what's the ram?secret...big secret.

[funkflix]

Yes, the Trfc of 11 is impressive, this sticks must be handpicked out of 100 sticks or more... or we will see new ICs.. UTT CH5 can't even handle Trfc of 12, so it must be BH5, tbh old BH5, so why it is so a big secret?

[don_vercetti]

next week when i get my CPU back, i reckon i could match that. my Geil BH-5 can do 265mhz with 3.2v (3.24v real), and tight timings (not stable in 32m or p95) but i'll certainly have a look at matching that. When can you reveal to us what is in those chips? Looks like a good thing.
