HYPER X worth it?

[syberspy9]

with my setup (look below) will buying some kingston hyper x 2x256 drr400 dual channle help me any im curently runing some samsung ddr400 2x256 dual channle pc3200 its the best stuff that asus recomends for my mobo.
will it be worth it? or is there somthing better on the market than the hyper x ?? what will work the best im my rig??

[syberspy9]

well.............

Well I've got 2 Samsung sticks running dual channel now, and I'm going to replace them to HyperX. The Samsung are pretty bad. My Abit IS7-E board reads the SPD as 3-3-3-7 but in practice they run stable with no errors in Memtest86+ just at 3-3-4-7, what makes me think it's actually an Original Samsung which has the not impressive latency of 3-4-4-8... I'm going to get 2 HyperX PC3500 with BH-5 which will enable me to run 2-2-2-6 at 400MHz or even higher. You have an even better board than mine (I hope to replace mine to yours), so you can utilize even higher voltages (up to 2.85v if I'm not wrong) which will make you able to run a HyperX (especially a BH-5 one) at impressive speeds with low latencies.

So what I'm saying, in short is: get the HyperX; preferrably one with Winbond BH-5 chips (as opposed to CH-5). That is KHX3200K2 model and not KHX3200AK2 (the model without the 'A' is the better, BH-5 based one).

Oh, and by the way, about the Samsung... I do manage to overclock them at 3-3-4-7 up to 334MHz stable. Which is not that bad I guess for their low price.

[tenegg]

334mhz = 668 ddr? or you mean 234 mhz = 468 ddr?

[Oren]

Oops, a typo! I, of course, meant 234MHz (468 DDR). Wish I could have it at 668 DDR ;)

ok well im thinking ill whate until they make ddr 800
right??
because the ram runs best at the same fsb as the cpu
because right now my cpu is a p4 C = 800fsb and ddr 400 is in it so i should get ddr 800 when it comes out?? i have no clue

Dual channel DDR400 will have an effective bandwidth of single-channel DDR800 -- hence so long as your dual-channel ram is running at 1:1 speed, you are getting the full bandwidth of your CPU.

Thus, a 2.4C at stock speed will be fully saturated with a pair of DDR400 sticks in dual channel. A 2.4C overclocked to 3.6ghz would need a pair of DDR600 in dual channel to fully saturate the memory bus. Since it's pretty damned hard (but not impossible) to find DDR600 ram, you usually end up running the ram at a different divider (such as 5:4 or even 3:2)

[Sophisticated]

the p4c's are quad pumped thats why it comes out as 800FSB for cpu...memory isnt quad pumped...only doubled thats why its called DDR = Double Data Rate....if the memory runs at 400MHz pc3200 it can run in sync with 200FSB of the cpu which is doubled at the memory like i said above which gives you DDR 400...if that makes any since..

[syberspy9]

okl i have a 2.4C running at 10% oc controlled by AI overclocking on my asus p4c800-E and i have no clue what to set my ram ot so i dont oc it so what should i do to get the best conection preformance

the 10% oc is like 2.66ghz

[syberspy9]

so if the 2.4C runs a 800fsb then what tiep of memory will run in sync with it ddr 400 (as Sophisticated wrote?)

so ddr 400 has a 400 fsb? or is it 200fsb X2 = 400ddr?

and the cpu is a 800fsb? or is it 200fsb X4 = 2.4GHZ C(800fsb)

The 2.4C is 200FSB X12. So the basic FSB is 200MHz, but since it is quad (X4) pumped bus design, it's actually 800FSB.

DDR400 will run in synch, as it actually operated at 200MHz (X2 for being DOUBLE data rate memory, hence DDR400).

DDR is 200MHz x 2 = 400MHz Pc3200

CPU is 200 x 4 = 800FSB..but we go by the multiplier listed in the Bios which would be 12 x 200FSB = 2400MHz (2.4GHz)

When the Memory runs in sync and the FSB x 12 is raised the MHz of the memory also raises it...the only difference is you times DDR by 2 since its Double Data Rate...That gives you the speed of your memory....when running divider 5:4 the equation is like this...

FSB/5x4 = Memory speed x 2 same goes for 3:2 divider

so if your running at 230FSB on a 2.4c with 5:4 divider you will come out to this

230FSB/5x4 = 184MHz x 2 = 368MHz Memory speed total

[mattspalace]

Seems like you're pretty new to overclocking OP, so I recommend getting some PC4000, setting a 1:1 ratio (or sync), and changing the FSB to 250. This will give you a 1GHz CPU bus and DDR500 (PC4000) with the memory. Should be an easy overclock. Mine is doing just under 3.5GHz 24/7.

KINGSTON HYPERX 1024MB DUAL CHANNEL KIT PC4000 2X512MB DDR 500MHZ 184PIN $666.65 !!!!! man im looking at memory that is max 250$

ok i get most of all that exept for

FSB/5x4 = Memory speed x 2 same goes for 3:2 divider

so if your running at 230FSB on a 2.4c with 5:4 divider you will come out to this

I dont know any thing about timmings.

so im getting a 2.8C (i think its better deal than 2.4C)

this is my fav. store (canadian)

http://www.ncix.com/products/index.php?majorcatid=101&minorcatid=105

so i was looking at one of these

KINGSTON HYPERX 512MB DUAL CHANNEL KIT PC3200 2X256MB DDR 400MHZ 184PIN $245.10

KINGSTON HYPERX 512MB DUAL CHANNEL KIT PC3500 2X256MB DDR 433MHZ 184PIN $224.58

its max 250$ so im now seeing that i wont get the bh-5 or bh-6 chips and lots of other things i wanted but the min must be:
pc3200 ddr400 2x512mb dualchannel

(the mobo is a P4C800-E)

[Sophisticated]

230FSB divided by 5 times 4 equals 184MHz times 2 equals 368MHz(total memory speed) i times the last part by 2 to get the total memory speed...get it yet???

[syberspy9]

ok then why do ppl say lower timings better?

wouldnt you want somthing like 1:4 rather than that 4:5

but tell me i need to know about the reas i said rather than timings right now

[Sophisticated]

1:1 5:4 3:2 are dividers...timmings look like this ... 2-2-2-6, 3-4-4-8 and other combinations...the 2-2-2-6 timmings are low and the best you can get..also known as tight timmings....www.Corsairmemory.com has a great tutorial on Memory basics and such Explaining all of these things

[Sophisticated]

go with the PC3200 and run it in 5:4 Divider as you most likely wont be getting far past 250FSB or 250FSB at that..

[syberspy9]

how do i run it at a 5:4 driver i dont know how to run memory

[syberspy9]

o and i dont get this y the pc3200 y is it more $$ the pc3500 runns faster well look at it i just dont get it?!

in the p4c800-e BIOS under jumperfree configuratin under AI overclock Manual menu the DRAM freq. listed as [Auto] set it to 333 = 5:4 & the pc3200 is more expensive because it has tighter timmings also its a more common to buy RAM so they raise the price to get profit..

[coachphil5]

before you buy hyperX pc4000 check this out.

http://www.legitreviews.com/reviews/hynixvssamsung/

kingtston value ram 2x256 modules are on sale for
$79 at bb right now with the

sorry the review is for the 1g setup, but these overclock to 260
and beyon easily.

pc4000

[syberspy9]

yea im going to go with the pc4000 and probibly 1gb of it 2x512

but now that i have ran ino a halt in the sale of my 2.4B and my oem samsun ddr400 pc3200 i having to hold on until i can go get the ram but thanx for the info guys one last thing if down the road i was to buy ram rather than right now what would be the best that for my sytem if im running a 2.8E and my P4c800-e??
like my fsb on my cpu would be 800 so what do i want my ram at?? and if the (PC (ram)) keeps going higher what would be the best like example ddr800 (cuz the cpu fsb is 800 that would be in perfict sink right?) and what would it be pc5000 or somthing

just what will be the best ram for that cpu and mobo?
