P4P800 and Winbond CH-5: Yes or No?

[TechTones]

I'm hearing the CH-5 sticks aren't compatible with the 865 chipset.

Is this true? No one is running this board and this ram OK?

I seem to remember that when these CH-5 sticks came out people were saying they were good for Intel rigs.

[JCviggen]

I'd avoid CH-5 sticks like the plague m8...

horrible timings, and they dont run very well (or not at all) at 5:4 setting

[TheDude]

I seem to remember that when these CH-5 sticks came out people were saying they were good for Intel rigs.

I was under the same impression. You won't get the real tight timings of the BH-5 sticks, but that's ok for P4 CPUs from about the 2.4 up to the 2.8.
Unless there is something in particular with the 865 that I'm not aware of?

ahh I see JC cleared that up...while I was hunting and pecking.

[TechTones]

Ok thanks

I wonder what Kingston plans to do about it then and even Corsair. All the latest Hyperx 3500 is CH-5. So if they're only so so for AMD, Kingston and Corsair have no product for Intel unless they go Hynix I guess.

[RichBa5tard]

So, what is good, affordable ram to go with intel 865/875?

[TechTones]

Well

I'm running the old Kingston that say "Kingston 4.3" on them and they run fine on the Asus 865. I don't know if they're really Bh5's or Hynix chips.


Funny thing is I tried two sticks of TwinMOS BH5's in the P4P800
and it didn't really like them. I know hard to believe but the scores were horrible compared to the Kingston 4.3's and they didn't OC as high either.

I'm working off of 2.85v only. I think I'm forced to do the mod.

Asus has a great board here. They could have had the the real only ticket if they had a 3.20 Vdimm. Can you imagine that?

[nutso]

Do the mod and you can take it up to 3.1. Just like Macci or Zroc said (can't remember who) just jam the voltage right the arse!! You know how....

[TechTones]

Ya I think I will

Maybe I can make the sticks that I have sing. :banana4:

[mrzee]

Like this? Hyper X3500@3.2v

[Amoeba Assassin]

Id get some muchkin pc3200 or pc3500 level II

[TechTones]

I just stuck 2 x 256 CH-5 in my AMD rig. Booted right up at
2-3-2-6 using a 221 FSB. It rebooted at 2-2-2-6

I got these as part of deal so I took the Ch-5's. It's not like I paid full price for them. They are HyperX 3500 but I took the spreaders off them.

They are getting 3.02v in the Abit N2.

I have 4 x 256mb sticks of the old HyperX in my P4P800.

[Dirty_Punk]

i have 1 stick of HyperX PC3500 with CH5, good unsed amd setup (242mhz 2-2-3-7 full stable) but on P4P800 if i set 5:4 divider the mobo won't boot... changing the stick with a a-data pc3200 with bh5 all works fine

the same on soyo 875p

[nutso]

It's to bad they don't make BH-5 anymore.

My understanding that the CH-5 was made to take a lot of volts so, if you undervolt it like say 2.85 and below, it won't perform for you. I heard about a stick of Twinmos PC3700 with CH-5 had a sticker on it that said minimum voltage is 2.7v. If that is true, it only stands to show that you need about 3.1-3.2 to o/c the stick.

[x2sandman]

Now that i think of it, this could be the problem i am having. I have 2x256 HyperX pc3500 in a p4p800-delux with my second 2.6C . Neither of them can do over 3ghz, so maybe it is my ram holding me back, becuase no matter what voltage i give the CPU i can't get above 3ghz

[nutso]

Just give the memory area some active cooling and you should be alright.

[x2sandman]

well the thing is, they can do 230mhz 1:1 on my 8rda+, so i know it's not the memory, and i don't have another intel board or chip that i can try out to see which one is the culprit.

[q149]

I am having major probs with my 3200l ch5l and IS7.. i booted into windows at 250 fsb with 3v and ran 3dmakr with 236 fsb 2.8v with these sticks on an nf7.. on my is7 i can't pass 250 fsb no matter what with any ratio timings or anything. I suspect it has to be the ch5's so i am getting some bh5.. I dug up an old thread somewhere where macci was getting stuck around 255 fsb with any settings with 2 different types of ch5 when he could go 300+ fsb with bh5 sticks.

[nutso]

Try it with 3.1 or 3.2.

[TechTones]

I have my HyperX CH-5's doing 233 in my Abit N2 but at 2.5-3-2-9
and 2.9v Vdimm in the bios which is overvolted severely at 3.02v

It looks to me the CH-5 in the AMD setup is not too bad, but TRCD must stay put at 3 for complete stability. But, in conclusion this are not quality sticks. Luckily I still have 4 sticks of BH5.

2 x 256Mb of the old TwinMOS 3200 BH5's and
2 x 256mb of the Buffalo 3200 BH5's.

In fact, I think Newegg is still selling the Buffalo 3200 Winbond modules for like $46


**EDIT*** Yes they still sell them guys!!!!!

[nutso]

Hard to tell TechTones if those Buffalo's are single sided. Can you shed some light?

Your pic of Newegg's memory selection shows to be "CH-5" by the pic so be careful here. The $62 stick is BH-5 as CAS 3 via the pic and posting.

Yes they are single sided. 8 chips on one side.

[TechTones]

It may be possible they are CH-5 but so far no one I know has gotten Buffalo 3200 with Ch5 chips on them. My buddy just bought the 512mb 3700 and it was Bh5 too.

Of course you take a chance but guess what? You can RMA to Newegg no problem.
