khx3000/256

[biohead]

hi
is the khx3000/256 (2-2-2-6-1) good for 250fsb? I've seen pc3200 do it but can this do it too? The khx3200/256 (so without the "A" = bh-5) isnt available in my country (yet), only the "A" version of it. So would this pc3000 bh-5 be a good choice?

later,

[Techmasta]

How much vdimm will you be able to give it?

[biohead]

wow thats a quick reply lol :)

its going to be on a DFI Infinity board so it will be 3.3v I think

[macci]

bh5 is bh5, 3000 or 3200 doesn't make a difference. its good stuff :)

[Mrstickinit]

Yep good stuff!!!


Macci,

You gonna break 10,000 today??? :banana:

[charlie]

Macci,
But the $25,000 question is :D
Is ALL KHX3000/256 BH-5?????
Some say NO, but I'm sure you know the facts!
Kingstons .pdf says 5.4nS Winbond modules (=bh-5)

C

[biohead]

well the pc3000 and pc2700 from khx are BH-5 I think, but the pc3200 is in two different versions, the KHX3200A/256 and the KHX3200/256. The one without the "A" is BH-5 (2-2-2-6-1) and the one with the "A" is something else (2-3-2-6-1). But my country only has KHX3200A/256 (or 512), so Im looking for that pc3000. Is that good for 250fsb+ too?

byez :)

the kingston site says its 2-2-2-6-1, isnt that a recognition of the BH-5 modules?

I agree.... but there have been RUMORS thst some sticks are NOT.

C

[biohead]

I'd say rumors without proof is bs ;)

[macci]

KHX3000 is all BH5/6 AFAIK.
IIRC people have found samsung chips from KHX2700 series thou.

[Mrstickinit]

IMO you can never be too cautious in this business. I say find out for sure before spending your cash. KHX3000 IMO is still great memory.

[`schr0et]

Bh-5 is not just BH-5.

There are limits to BH-5 oc's based on quality of PCB.

Kingston seems to provide high quality PCBs, where as sometimes Corsair Bh-5's can't touch FSBs that Kingston HyperX can do.

I have Corsair XMS3200LL 512 Dual Channel Kit rev 1.1

AND Mushkin lvl 2 Black 3500 1 Gig kit.

I love my corsair dual channel kit, does 245 with only 2.9 VDimm, but I've seen others not able to hit past 230 without 3+ volts... I guess I just got lucky.

BTW Macci YGPM :toast:

[charlie]

Is there ANY way to ID KHX3000 as BH-5 WITHOUT ripping HS off?? Something that can be done in a store??

Thats like saying is there any way to see if the 9800SE video card you bought is a 9700 or 9800 layout without actually opening the box.

Unfortunately the only identifying tool that we've found here was the marked A and Non A for KHX, obviously you know that NON A is CH-5. But whether you get BH-5/6 it shouldn't really be much of an issue.

Unless of course you get CH-5, then your going to hell cause no matter how many volts you put thru CH-5 it won't make a difference cause those stupid chips have voltage regulators built into them :(

[Mrstickinit]

I hope the mem manufacturers are reading this thread and take heed. All of us would like to know EXACTLY what we are buying.

[Kalway]

Yeah, they're taking note. Taking note on how to make it harder :P. They're gonna use contact cement on those heatspreaders now so you'll never know!

As for PC3000 KHX, it's going to be good chips no matter what. I doubt you'll get any sammy stuff any more because that should all be long gone. It's more than likely BH5/6 which is good for 230mhz+

[biohead]

yeah I'll email the store with the khx3000/256 to be sure if its BH-5/6. I dont want to spend my money on something "useless."

[Soulburner]

I doubt they will even know what you are talking about.

[PGgagne]

LOL me and my cousing were at shop and the were like what the heck is BH5/6 lol

well its worth the try :P I said it could be checked by removing the heatspreaders. Or am I wrong?

[Mrstickinit]

You would be correct. The mem chips will have BH-5 or BH-6 on them.

Learned that today here on the forums! :banana:

[biohead]

yay happy me :D

:banana: :banana: :banana:

btw nice smileys here :cool:

I dont believe the PCB affects the overclock much at all, because there have been reports of single sided, dual sided, kingston/corsair/a-data/buffalo/etc all doing good or bad.

If anything its more dependant on the motherboard.

[biohead]

btw do these BH-5 chips have a limit or are they willing of doing any fsb/timings at high voltage (such as 3.3v)?

[STEvil]

bh-5 is bh-5.

I don't know why but that quote sounds classy...

But yes its merely "the luck of the irish" type of thing... meaning there are good and bad BH-5, but pretty much all BH-5 should be able to do 230 FSB with 3,3 VDimm I would think...

[STEvil]

I would hope so.

My BH-6 do 230 2-2-2-5/6/11 with 3.1v :D

[biohead]

YAY I found a store that sells KHX3200K2/512 (2x256mb) kits. They are BH-5/6 because they have 4.6ns cycle time and are 2-2-2-6-1 :D
:banana:
AND I finally found a store with a 92mm tornado :D but then again check out my other thread: "no SLK-900U on a DFI Infinity, what now?!"

[sjohnson]

Here's a pic of some recent khx3000 from Newegg, heatspreader removed. Received about 3 weeks ago. Anyone know for sure who made the chips? Notice that there are four chips on each side of the PCB making it double-sided, so far these sticks are crap for O/C for me, though I haven't given up on them yet.

[Danne980]

This sound a bit worrying for me.
I am choosing between:
OCZ EL Platinum Limitid edition pc-3200 2x256
and
KHX3000

What is the best choise you guys think?

(cant find much info on the OCZ mems)

[STEvil]

I wouldnt surprised if they were samsung or something similar...

Those two circles you see there means that they are BH-5/6 FYI

How much volts are you giving them?

And whats your highest FSB?

[sjohnson]

In my infinity (which does 256 unstable, 246 stable with my ancient TwinMOS BH-5) the two sticks did only 210 memtest/memtest86/prime95 stable at 2.9v. More volts made them behave worse. Two weeks of burnin at 2.9 and higher made no difference, higher than 210 and tons of memory errors.

Now here's the interesting thing. I took off the heatspreaders this AM, that pic was taken 5 minutes after removing them.

The sticks are currently running 208 @ 2.6v. I'll post more after I find the limit but WTH, removing heatspreaders did that? They ran like crap last night with the spreaders on and 2.7v.

BTW, the "thermal tape" used was only touching the three or four of the memory chips, and then only about 5-10% of the chips it touched. The "tape" might be some kind of engineering marvel but it looks like double-sticky duct tape. How in the heck could removing the heatspreaders allow a .3 drop in voltage for the same O/C

[`schr0et]

Beats me man :rolleyes:

So once you removed the heatspreaders theres no way of puttin em back on?

[sjohnson]

They could be put back on, the clip came right off and like I said there was almost no contact between the heatspreader tape and the chips. Some slight marking of the blue anodized surface of the spreaders where I pried off the clips but taking them off was very easy.

[STEvil]

Maybe the heatspreader was grounding out some of the ceramic capacitors?

[Shade00]

Interesting. I just got two sticks of HyperX PC3200 (non-A, of course) and they're acting pretty iffy right now. They error out in memtest at default speeds with less than 2.8v... I'm wondering if I should remove my heatspreaders... they look so cool. ;) I haven't had time to push these sticks, but if it'll help, I'll take the heatspreaders off.

[STEvil]

before you take them off look carefully at the DIMM edge-wise and see if you can see any of the small brown capacitors making contact with the heatspreader

[sjohnson]

STEvil - I know my pic makes it look like I cut off the top edge of the khx3000 in the pic but it isn't. There are no caps or other circuit components along the top edge of my sticks, anyway. Just blank PCB...

[STEvil]

look at the ends of the stick.

my XMS3200 has caps on the top and inbetween the chips (double sided) and at each end.

My Trancend PC2700 has a couple big ones at one end and the SPD chip on the other which would interfere with heatspreaders for sure..

Here is a pic of my Trancend stick.. shows the large caps and SPD chip

[sjohnson]

My khx3000 is up to 215 FSB @ 2.7v now error-free. It's now higher than ever before, no matter what volts.

Definitely *something* about the heatspreader(s) held my sticks back before, certainly could be some kind of short caused by the spreaders (or more likely, the thermal tape, the tape kept the spreaders well away from any circuitry).

That "tape" still bothers me. Sticky gray film sandwiching a cloth center. The spacing between fibers of the cloth is about 2mm, forming approx 2mm square voids full of air - and we all know that air is a relative insulator.

[celemine1Gig]

If the heatspreaders would indeed have shorted some of the circuitry on the PCB, then the RAM would have errored even at standard MHz and timings!!!
It's just a heat problem, when the idiots in the factory think they do not need to put the spreaders on right, with a tight fit. If not all chips make good contact to the heatspreader, the spreader works more like a heatshield and keeps the heat in the chips. Then, the chips that do not make contact to the spreader, fail at a certain speed and voltage and if one chip fails, the whole module fails logically. ;)
That all about it. You just improved cooling by removing the heatspreaders, although it might sound strange, that's how it is. :D

[sjohnson]

It doesn't sound strange at all. It's exactly what I thought but I didn't want to move this thread into a discussion about heatspreaders, yea or nay ;)

[Popcicle]

... if you read he Kingston pdf. the W 45 on their

chips stands for Winbond 4.5 NS which is BH-5.

[Arkangyl]

sorry bout the hijack but does anyone have experience with the Kingston Valueram line? I've heard good things about them having BH-5/6

[`schr0et]

Ya people have gotten BH-5 with the value ram, but since BH-5 is in such demand and with no real supply of it the chances of getting BH-5 on value ram is slim to none nowadays.

[naTTen]

I have kingston khx3500/256 and thay max out at 218 mhz fsb at 2-3-3-7 timings. They are unstable at 219 and raising vdimm doesn't help!!
Running it at 2,77 on my epox 8rda+ rev 2,2
Anyone know anything about this?

[DjTonic]

My PC2700 (BH-6) is runing at 220FSB 2/2/2/5 vith 2.8V 24/7. I'm wondering how farr it will go with cca 3.2V :D

[TheWeaseL]

...Hmmm, I should rip the heatspeaders off my 2x512 KHX PC3000...Maybe help me get higher yet...

[STEvil]

A grounded out cap would just cause instabilities more than complete failiure...they only handle a small amount of voltage and amperage so the leak would be minimal, probably only enough to affect it beyond stock speeds really...

[biohead]

when I got me myself some Revoltec ramfreezer (copper) I couldnt get them off anymore. They were very tight and allmost glued on the chip. I'd say the KHX heatspreaders are garbage if u can pull them off... heatspreaders are better than NO heatspreaders u just have to attach them well... I would not recommend pushing 3.3v without heatspreaders no way :slobber:

Just put a fan over them. They'll be alright.

[naTTen]

I removed the heatspeaders on my khx3500/256 yesterday and the had ch-5 chips. Not very good at all.
Have to get my hands on some bh-5 memorys

[sjohnson]

Up to 230@2.9v on the khx3000 now. I've gone from ready to RMA at 210 max to very satisfied with the performance - just from removing the heatspreaders.

[Endre]

Just got two of these sticks.The code on the ICs is the same as on sjohnson's, hope they're that good (can't test the in a while).

[biohead]

o thats cool :) I guess 3.3v would do 250+ with these chips... :toast:

[Phyrox]

Hey guys I ordered 1x512mb KHX=3200 for my K8npro - does this board really care if I use 1x512 or 2x256 oc wise? looking for atleast 2.6ghz under mach2

[sjohnson]

Originally posted by Endre

Up to 239 FSB@3.1v now, max the DFI Infinity can do is 3.3v. I'm looping the Sandra memory bandwidth bench for 24+ hour stretches (no memtest86 since I have no floppy and the CD/ROM is dying). I've gained 6 FSB in six days - going from BSOD at 233 FSB to stable in Sandra at 239.

I'm really glad I took off the heatspreaders to post a pic asking what I had, big, big difference in overclockability :)

[naTTen]

I have removed the heatspreaders on my khx3000/256 and i can "almost" do 200 at 2,9v 2-2-2-11. I haven't used them som much yet so i guess i need to burn them in. I could actually complete 2 whole runs in memtest86 at 200 fsb :) after a few hours use

[Formann]

My KHX3000/256 did 220+ 2-2-2-11 in my nForce2 rig, but in my A64 rig all i get is BSOD.. even when running 200 2.5-2-2-6 @ 3.1v

I remember reading something about dobbelsided KHX sticks not beeing stable on A64 when OC´ing.. anyone else heard this?

I think it was macci who wrote it ?

[enigma]

Hey guys I am not 100% sure but I believe that I read somewhere that when they end in 45 they are not bh5 and if they end in 50 that they were. Any heard of this b4?

It was mentioned in an other thread, but it's not correct.

[enigma]

http://www.abxzone.com/forums/showthread/t-62098.html

Just looking at that thread.
So what is the difference between the 45 and 50 then?

[charlie]

there's more to it than this...
you have to anaalyze the performance and look at the date codes on the remarked chips. My week 51, 2002 BW-50 are certainly BH-5... possibly because they do 240-250 2-2-2-5 at 3.28V or possibly because if Kingston remarked them in 12/02 it's unlikely BH-6 was even in widespread use, and CH-5 wasn't even around yet...

[`schr0et]

My sticks can do 265 FSB 1:1 @ 3.42 Volts 2.5-2-2-5-12-16 on my A64 3200+ Shuttle AN50R V1.3 9800 Pro...

Now I wanna remove my heatspreaders cause I'm just so damn temped cause they've performed so well for me... and that the heatspreaders are warm to the touch cause of the 3.42 volts :-\

Charlie if you could post a picture/ somewhat detailed directions as to how to remove the darn heat spreaders? I tried using a box cutter from work and I ended up just scratching my beautiful KHX :(

[sjohnson]

Use a jeweler's screwdriver at top edge (between the spreader and the clip) to lever the clips up. There's a small gap between the clip and the spreaders along that top edge (the edge that is on the other side of and complementing the edge you stick into the DIMM slot). Once you get the clip to move up a bit it's easy to remove them, just pull them off.

You could put a piece of tape on the spreader where the screwdriver levers the clip if you're worried about scratching.

Then either pry off the spreaders or use the freezer like charlie did.

Clear?

So the key to a high memory overclock is to change/replace the information that the manufacturers put on the Dimms with your own specs?

I'll have to try that!! :lol: :rotf:

last week I got a stick khx2700 512mb hopping for bh6. In my nf7-s it did 190mhz 2-2-2-6 at 2.8v but at 200 it was error free only 2-2-3-6 so it is not bh6. In my brothers epox-648 it was prime stable for 5+ hours at 166mhz 2-2-2-6 but 3dmark was not benchable and sandra memory bandwidth gave me blue screens. I was surprized since spd was 2-2-2-6 @166 and it was also tested in my nf7. But when I set ras to cache 3 (2-2-3-6) everything was fine. So khx 2700 (not A) is not bh6 :(
