NF7 + Corsair/HyperX

[InfoManiac]

Hey guys,

I´m buying a NF7 (not NF7-S) v2.0 in the next days.
I will also buy a new RAM. I was looking at a hard store here and I´ve found two different modules (both 256MB) at similar prices.

HyperX PC3500 rated at 2-3-3-7 1T and
Corsair XMS 256MB PC-3500C2PT rated at the same 2-3-3-7-T1

The price differenc is minimal. But I´d like to know which one will overclock better with tight timings with the NF7 v2.0

Need Help......thanks
;)

Definetley grab those Corsair XMS3500C2!!!

Those are BH-5, the HyperX PC3500 is CH-5.

Definetely grab the Corsair XMS3500C2 256 sticks, they are BH-5 and will run 2-2-2-6/11 timings 230+ FSB @ 2.9 VDimm.

The HyperX 3500 is CH-5 and will run as they are stated, if not worst :(

But both of them are ratted at the same timings/voltage. HOw could that be possible??

I´d also like to see people who has these memories posting their results. That would be awesome

Thanks

Well I have Corsair XMS 3200LL rev 1.1 2x 256 sticks BH-5
I also have 2x 256 Corsair XMS3500C2 rev 1.1 BH-5
I also also have 2x512 Mushkin lvl 2 3500 BH-5

see where I'm going with this? ;)

BH-5 = higher the volts the more gains you get.

2.6 VDimm = 200
2.7 VDimm = 217ish
2.8 VDimm = dunno
2.9 VDimm = Max I got stable 230
3,3 VDimm = 260 on infinity board running on my brothers rig as of date

[Aldus]

The corsair are NOT BH-5. They only Corsair that is BH-5 are the rev1.1's which those sticks are not. rev1.1 sticks are rated at 2-2-2-6 not, 2-3-3-7.

[nutcase]

you guys better check it on the Corsair..

If it is Marked CMX256A, it is CH-5. If it is Marked CMX256, then it is BH-5...

[`schr0et]

Um, please guys if your not sure on what your talking about don't post random stuff.

There is only one type of Corsair XMS3500 sticks and they are rev 1.1

Corsair stopped making 3500 sticks a long time ago, which is why it is so hard to find them.

All Corsair XMS3500C2 = BH-5

You guys are referring to Corsair XMS3200, which based on revision is CH-5 or BH-5

[BigJuri]

Only the Rev. 1.1 has BH5-Chips, all the others have CH5. If the Kingston have BH5, then take them. If not, I would say Corsair is the better choice.

[WinXP]

NF7-S v2.0
Kingston HyperX PC3500 2-256meg sticks, runs 218sb with 2.9v at 11-3-3-2.
Corsair XMS PC3500c2 2-256meg sticks, runs 235fsb at 11-2-2-2 at 2.9v.

The Corsair smokes the HyperX hands down. My Corsair XMS PC3200c2 is better memory than the HyperX PC3500.
Now runing the same Corsair in my DFI Infinity Ultra A+ at 250fsb at 11-2-2-2-2.

OMG your gonna make me pull my hair out!!!

Dude seriously READ what he posted, he said he has to choose between Corsair XMS3500C2 or KHX3500, as I stated 7 million times before there is only ONE type of Corsair XMS3500 and they are BH-5 sticks.

[InfoManiac]

OK, this is the module I´m talking about

http://www.rumo.com.br/lojas/00000786/prod/CorsairXMS256_3500G.jpg

Model#: CMX256A-3500C2PT
Rated at 2-3-3-7 1T


So, is this the one? (BH-5 or not?)

Yes that is BH-5, don't mind the 2-3-3-7 timings.

Corsair XMS3500 hasn't been produced in so many months that the timings are way off. If you note newer BH-5 sticks that are advertised 3500 speeds they say 2-2-2-6 timings, that is because marketing for the BH-5 modules weren't as tuned in as they are now.

Do not worry about getting the wrong item, as long as what your purchasing is Corsair XMS3500C2 you are guaranteed 100% getting BH-5 sticks.

[Drisler]

lol ...take it easy PR:p:


All XMS3500C2 are in fact BH-5

[asim]

Sorry to jump. But are you sayin any type of corsair xms pc3500 is bh-5?

[Drisler]

Yes ...all 3500C2

[asim]

Wow theres one place in the uk still stocking Corsair Platinum 256MB DDR XMS3500 CAS2

Imma buy 4 sticks. hehe. Although i doubt clocking 4 sticks at once is even gonna work. but can sell a couple

[BigJuri]

@PRanganathan: Don't freak out completely, I had 3 Threads open and saw your post after i wrote mine. :)

[Dud3!]

I vote for Corsair XMS, that's all I would buy, and what I use.

[asim]

Seems i found a place that have 2 sticks of 512mb xms3500 they aint platinum.

Its this one here. If anyone could give a quick look. Imma buy a couple of sticks

My apologies guys, it was getting frustrating trying to help people out and people repeating the same thing over and over after I gave them the answer to it already :(

But I have my coffee now so I'm nice and relaxed :toast:

EDIT: Yes those are BH-5 sticks, remember all Corsair 3500 models are BH-5 100% guaranteed.

[InfoManiac]

Thanks PRanganathan, you were very helpful :-)

I´m going Corsair :-)

[asim]

One last question. Whats the difference between the platinum and the regular sticks of corsair?

[Drisler]

No difference ...

bling bling looks better though. :D

[asim]

Well thanks alot guys. Jus placed my order for xms3500. Will be using these sticks with my mobile chip to allow for the high fsbs.

Ive got two brand new ocz pc3500 sticks sittin here which i got back from ocz cause my old ones needed rma'in. Guess i'll run those in my 3.4ghz at stock :D

Now if i can get some money together i'll build that second rig.

Thanks again. didnt know all xms3500 was bh-5. No hesitation in my order.

Drisler is absolutely correct, the bling bling factor is important to some of us (me) because we want our rigs to be pimpin ;), but other than that the plt and black have no differences between them lol.

[nutcase]

Just to let you know, Here is some interesting Info:

Just went and picked up some Corsair and here is what it has:

Corsair CMX512-3500C2.. Has BH-5 chips on it.. It is also marked Rev 1.1

Corsair CMX256A-3200LLPT.. Has CH-5 chips on it..It is marked Rev 1.2

Thought I would pass it on..

[STEvil]

1.1 is very important.

[blinky]

yes the revision is the important part, and the reason that all XMS3500 are BH5 is that theyre all v1.1 which means it was made during the time that corsair used BH5 in their dimms. if you guys hadnt noticed, theyre new ram, the XMS pro series doesnt have a pc3500 speed in it

[BoGuS]

Interesting thing about those sticks.... allways a B**itch to get the right ones....

Now after alle my speculations about what sticks to get, i finaly desided some time ago mind you, on the 2 * 256 Corsair XMS3500C2 and i was told also then that they would rock my world, but they only runs run @223 and thats the best they have rided ever, even when i set the multi really low... even tryed 2*, and no go, they run @2,9 volts and the system is fairly normal air cooled @Mhz 9 * 223 @41c.....

so whats wrong ?

Congradulations welcome to last year, its a well known issue that ABIT NF7-S V2.0 (the newer ones) have a 225 FSB max without vmods.

You need 3v-3,3v to make those BH-5 sticks fly. You would need to do a VDDmod + VDimm mod

[BoGuS]

Okay... so inlighten the less perceptive ;O)

what are VDDmods i know about the Vdimm (ram), but dont know about the other one...

and what speed can i expect with that kind of volts on the Vdimm... you should know that i am building a custom watercooler so speed/volts for both would be nice

B/

[WinXP]

Check out mods here:
http://www.motherboardfaqs.com/article.php?15.255

[asim]

Well jus got a call from the company. We dont have any corsair instock, website error :mad:

Back to lookin for somethin else then

My apologies, I have fits of anger in the morning when I don't have my coffee :rolleyes: .

Ok well the NForce2 m/b's have a problem reaching high FSB due to two (2) things, a low VDD (chipset voltage), and a low VDimm (Ram voltage), to fix those two you would need to volt mod.

Both are relatively easy, if you need answers on how to mod your board then go to www.motherboardfaqs.com they have a very good guide for the ABIT NF7-S V2.0 and EPoX 8RDA+

After volt modding, 240+ FSB is guaranteed if you do the mod correctly. running say 240/245x10/10.5 isn't hard depending on how high your CPU will be able to clock.

Things you need to do the mods correctly are and not limited to:

15W Soldering Iron
Multi Meter
small dia. rosin core solder
Soldering iron resting "station"
1K/5K/10K etc Variable Resistors
20-24 gauge stranded/solid copper wire

If you have any more questions feel free to ask :toast:

[BoGuS]

PRanganathan:

Ya well we can all get a bit off in the morning, just a typical monday ;O)

Well i know of the mods, just did'nt know what VDDim stand for thats all....

well i think my cpu can handle quite a bit..., since its running on default volts now, and if it burns i have a spare....

so 240 should be in the house, but at what voltage 3.1 ?

and i have seen some people pump over 4 volts through there sticks..... jesus thats insane.... but then again its XS right ? ;O/
@ what voltage should i be ready to order some new sticks and mind you that i only oc for 24/7 use....

Eh, people rarely fry their sticks, people have run as high as 3,8 for months with no problems.

You would mainly want to go for 3,2 VDimmor 3,3 VDimm.

3,1 will gaurantee your 240, 3,2 would gaurantee 245 stable.

3,3 would get you around 250 stable.

humm..... totally forgot to ask.... maby its not that good an idea to not get any sleep at all....... :0|

Just to clerify things my sticks are : CMX256A-3500C2 so are they bh-5 sticks ? and if they are what are the diference on those sticks with an 'A', and those w/out ?

Ya i know i'm not up to speed.... :O)

If you want to make sure, pull the Heat spreaders off. Corsair does not remark their chips and it will be easy to tell what chips are on it..

BUT, Check the REV number.. If it is Rev 1.1 IT is Most Definately BH-5..

And I now Agree With PR.. I AM Most certain that All Corsair PC3500 is BH-5..

[BoGuS]

ok... so we have established that all pc3500 are bh-5... jadja jadja..... but what does the letter 'A' stand for then ? since there are 2 types of pc3500 from corsair and they mark them diferently it has to mean something right ?...

B/

[`schr0et]

A is most likely just a generic mark, sometimes they use it to identify Black heatspreaders, sometimes to seperate 256/512 etc.

[InfoManiac]

OK guys
I´ve found out that finding the Corsair PC3500C2PT turned out to be practicaly impossible.
The question now is: What module now??
It must have a price very similar to the PC3500C2PT.

Help again :-(

The only place I have found that has Corsair XMS3500 is Fry's Electronics. And they only had the 512MB versions in stock.

you can go look at their website at:

http://www.outpost.com

But you would have to call them to see if it is still in stock..

[InfoManiac]

I`m not in the United States :-(
Can´t buy at Fry´s....

where Are you located?

I just saw somebody posted a link to some BH-5 memory in the UK..

[BoGuS]

They are also available in Denmark, so if your close by try contacting then about shipping....

Link but the site is in danish!
http://www.datatelpartner.dk/catalog/default.php?cPath=3&osCsid=1cc9390c5cbdee06062af942454790eb


ups, just forgot... they dont have any pc3500 modules... but pc3200 and pc4000....

BoGuS if your stuck at 223 you can L12 mod your CPU. Got me from 225 (stuck) to 245 without any vmods on my NF7-S v2 :toast:
If I mod it, I'll do the easy vdd to 2v since I WC my NB. The vdimm mod seems harder, which is why I'd rather beef my PSUs 3.3v rail.

Really ?... there was a link where one did a test and he only got a few mhz after the mod.... so figured that why bother....

OK OK
I just couldn´t buy the damn BH-5 ram. Neither the Corsair nor the HyperX

Now what? What ram now is cheap and overclocks well enough with tight timings for a NF7

Thanks

[LikwidKool]

you could go for the OCZ pc3200 Plat LE, which is bh-6 chips. Not sure how they fare on an NF-7, but if you have 3.0v+ vdimm than they should do well.

Or you could just try some ch-5 sticks and see how they do. I have heard some good things from the current crop of ch-5. I would pick some up myself, but I already have 4gb of bh-5, and 1.5gb of non bh-5 so no need for more ram right now.
