POLL: K6 overclocking - Retail vs OEM

[Ed_S]

Seeing a lot lately on successes & failures on the K6's, wondered if the success rate differs much between the retail-box and OEM versions.
================

Mine is a retail K6/2-400, o/c'd to 450 day one, 2.3 volts. Stock AMD fan. Will post & load W95 at 500, but get BSOD immediately. Would probably make it if I upped the volts. Has never been ran at 400.

[RobRich]

I've mostly dealt with OEM k6-2's and they seem to o/c just as well as the reatil chips. I actually haven't used a retail k6 since the k6-2 300 series. I running my current OEM 450 CXT 2.4v model 08 stepping 0c at 500mhz (2.7v) stable.

The best k6 to get right now is the new 2.2v 500's. Every person I know that has one has made at least 550 with just a decent heatsink/fan combo.

OEM K6-II 400 running 550@2.5v, these are the best buy by far http://www.sysopt.com/forum/smile.gif

Mine is an OEM 400 @ 450 (or 475). Can't hit 500 yet.

I've taken 16 OEM K62 450's (2.2 & 2.4v) to 500, as well as 4 retails. No apparent difference between the two.
The OEM 500 is another good one- I've gotten 4 of them to do 550 straight out of the box. Haven't tried the retail version yet... http://www.sysopt.com/forum/wink.gif

my OEM K6-2 333MHz runs at the moment @ 380MHz.

[denz]

Retail K6-2/350 oc'd @ 500/3.1V. But I don't see any reason why an OEM will be different from a retail chip. They all come from the same factory and pass thru the same quality checks.

[Andy_L]

retail 450@500 2.4v, retail 300 at 333 2.3v

[otheos]

OEM K6-2 450AFX @ 560 out of the box.
the first chip went back RMA (unstable at all speeds)

[neo_otyugh]

oem k6-2 400@473 (4.5x105@2.6 volts)
i only buy oem....prefer to get my own heatsink/fan

[alpha]

I have an OEM 350 and it reeks of gin. (bad thing)

[sharky]

K6-2 350 2.2V OEM o/c'd @ 450 and 2.5V

[Brydon]

amdk6-2 300@360
amdk6-2 350@400
amdk6-2 400@495
amdk6-2 450@500
All oem chips so I reckon there cant be much difference between oem and retail for overclocking success

[oblivion]

They are the same **** chips,except one is marked and sold for retail use,and the other is marked and sold for OEM's and the like
There is not a difference between the two except for price and warrenty

[deep_sky]

oblivion...
are you trying to be a pain in the a**? because if you are, you are doing a jolly good job at it. do you have some problem discussing amd chips? if you do not like them, then do not post any responses to them. we do not need to hear you smarta** remarks. if you have nothing good to say, then don't say anything at all.


to everyone else.....
i have an oem, and it does not overclock very well (k6-2 450 ahx), going to try to improve my cas latency on my mem to 2 and see if that will help the memory errors i get at 500 mhz....better fan on heatsink as well....

[oblivion]

Deepsky said "are you trying to be a pain in the a**? because if you are, you are doing a jolly good job at it. do you have some problem discussing amd chips"
Hey what are you talking about,all I said was that there is not a difference between Retail or OEM chips,I did not insult you or anyone,and furthermore I am refering to Intel and Cyrix and any chip maker as well.
What do you really think they give OEM's better chips and keep inferior chips for thier retail units so they have to horor warrenties on inferior products ?? That is silly. Do you even know how the chips are made?? I assure you they (retail/Oem) come randomly off of the same wafer and are no different.
I happen to love AMD(err well the Athlon at least)

Edit-Deepsky,setting your cas latency to 2 will not help as that is a high performance setting and it would only help adjusting the cas if you were OCing via a FSB increase (i.e.ram at 110 instead of 100)
rather then a multiplier tweak(and only then settin the cas higher then 2 would give you better odds-End of edit

when you state something in bold letters, it is taken to be emphasized and furthermore, swearing without using some asterisks is not taken to kindly by the admins. the way you put your statement sounded like you were being a pain just for the sake of being a pain. if that is not the case, then please modify the tone of your posts.

edit~
i will take that into account, oblivion. i tried to oc my 450 to 500 and it would not run stable no matter what voltage it was at. i just want to try to see what the cas latency setting does for my system. if changing it to 2 does nothing for it, then back to 3 it goes. i think that this chip is oc'able and i want to get every last drop out of this rather cheap system before i upgrade to the athlon.....

I was not trying to be a pain,just look at my other edits.....


Edit-This is how I caption all of my edits,unless it is to correct spelling or add a missing word ect. if I add new content I surround it with bold type,I am truely sorry if you thought I was being rude,I assure you it is not my intention,I just like to be clear with my edits so as to not have confusion about what was said in the past and how it was changed,that is all-end of edit

Back to the poll... http://www.sysopt.com/forum/wink.gif

OEM K6-2 400 @ 450 2.4v with a Global Win HS/Fan

Haven't tried anything higher yet.

When AMD fabricates a cpu, many are produced at the same time on a wafer board. The retail chips come from the center sections of the board, versus the OEM chips come the outer regions. Usually your best yields come from the inside sections, thus this process yields a better made cpu (in theory!).

Where we benefit is AMD's rigurous testing and sampling techniques, thus thoroughly inspecting each batch for defects. This provides us with extremely well made OEM chips that rival their retail cpu's.

AMD also offers a good warantee on their retail chips (equals more cost), and includes a properly spec'd hs/fan combo. While their cooling setup is not a good o/c'ing setup, when at defualt it does its intended job quite well.

AMD has followed this procedure for several years, and without major incidence. Thorough testing of each model stepping and revision is the reason we have ever increasing o/c'ble AMD chips, reatil or OEM.

Hey Robrich,I have heard that as well,but I have also heard from several very reliable source's that the better chip come's from the whole center of the wafer thing is a falisy,I am not saying it is absolutly wrong,I am only saying that I belive it to be wrong.I have seen exellent results with OEM chips and really no better with retail.

[RobRich]

You could possibly be correct with the newer revisions, as my information only applies through the 2.2v k6-2 300 fabrication technique. With the newer CXT and AFR/AFX revisions this may have changed. I will try to research this issue further.

As for the debate, buy a newer 2.2v 500 OEM chip. Most of these will make 550 with little effort at all. I would recommend a good hs/fan such as an alpha or globalwin.

[oblivion]

I suspect they are getting 500 yields from all of the k6-2's,and that unless you were bent on getting a chip that would do 550,you could just get a 400 and OC to 500,maybe more
'My cousin just got an AMD k6-2 400 on my recommendation(he is not an OCing type and not the tweaking type either)and it does 500 at 2.2........it would most likely do 525...maybe even 550 if he had mucho luck,but I am not testing his luck,as I can't be there everytime he gets a BSOD.
