Kingstone HyperX + 8RDA+ ?

Hello,

Please share your experiance with KHX3200, KHX3200A or KHX3500 memory running on Epox 8RDA+ (rev.1.1) How is it performing ?

I'm asking because last week i bought 512MB Twinmos (M-tec 50D chips)with hope that it will run DC with my current 512MB Twinmos (Winbond BH-5) but nope.... it was disaster... totally unstable at 200mhz with cl 2,5 even single channel no matter what voltage i set.

Now i'm thinking about buying Kingston KHX memory but i dont want face the same problem as with Twinmos (M-tec). Please post any coments about running 512MB sticks of HyperX on 8RDA+ SC or DC.


greetings,

frostmoon

At first I tried 190MHz 8,3,2,2.0 at default voltage SC - it corrupted windows profile
rising voltage up to 2.9V didnt improve stability at cl2... tons of errors in memtest. DC with my Twinmos BH5 was even worse
with relaxed timings 11,3,3,2.5 and 2.9V it could only do 200Mhz and i cannot say it was 100% stable. I was hoping much more from this memory. Its crappy comparing with my Twinmos BH5

My 8RDA+ is vdd moded and tested up to 225mhz SC synch. All tests were run at 1.8V vdd.

Lord Vetinari, are you using 2*512MB sticks ?

hi
I recall an issue being discussed here about problems with 512Mb sticks on the 8RDA+.
I suggest you search AOAForums. or w/google

50D is worse than 50B.

Thx for reply Ancient1

I konw that 50B is better than 50D... BUT as winbond bh5 as 50B is very difficult to find on a market now, if possible at all... at least where i live.

Reading quoted aritcle on OCZ site make me smile I'm not interested running memory asynch as they suggest... ... its nforce2 mobo and its loosing performance in asynch mode, i can't believe they wrote something like this



My main reason writting this post was to find how HyperX memory works with 8RDA+ not why MY Twinmos 50D does not work...
As stated at the begginnig my 512MB Twinmos BH5 works good with this mobo (up to 225mhz fsb SC) now i want to find another memory which can achive similar results and i thought HyperX could be a good choice. DC is not a must, I only want 1GB of RAM working at good 210+ fsb.


Thx for trying help me,
frostmoon

Thx TonyCarr

That is optimistic news

Did you try higher fsb ? What are your memory timings @200 fsb ?

EDIT:
One more question, when you bought your memory ? I konw that 'older' KHXs had BH5 chips now they probably dont.

When I had my 8RDA+ rev 1.1 I ran my 2 x256MB KHX3200 dual channel at 230MHz 6-2-2-2 with 2.9v without a hitch.

why not have a store prestest the ram they sell you. for a fee. ?
the problem with DC and OC is that they contradict each other stabilitywise.

Ancient1, this is difficult here in Poland, if you dont have a friend in a store (i dont have) there is a little chance to test products before buying or buy and then return product if its not working on your computer specially if its working on computer in the store.
I know one store near my town which is selling parts and i can return it if something is not working at my home. Unfortunatlly they dont have KHXs they can order it form me, but not for testing...

So im looking for a information here

ah.
ya ruzumyem mawe popolsku, lachego moye roziche yest(biwe) vpolska. jiduv vzamosch i volkovisk. ya yestesh v israel. no tak.

I know this problem. and you are doing right. u can use google too !! .

I myself would like to know since this question applies to me too. this issue is hard to know since we are talking about OCing and there are no guarantees for that. and also any finding won't be definite
I can tell you that if u CAN OC high you'd better have 1 stick. if you are staying withing mem spec than DC. but obviously that was not the case for you.
there are DC packs . 2 sticks in a package.

take the PC to a store with KHX 3500 and tell them to pretest it (at defaults) ?

the perf difference of timings are less than 2% and fsb ~5% or less. DC vs SC , as I recall gives ~8%.
