Any OC experience with Patriot 800Mhz Low Latency?

[bengkiam]

I just want to know its voltage setting for max freq and timing.

 

[stagepuppy]

not a max setting for me but a data point nonetheless...

Abit AB9Pro BIOS v1.4
E6400 @ 2.94GHz (FSB 367 x 8)
Patriot Low Latency PC2 6400 DDR2
2:1 ratio (only 734MHz)
2.1 v
4-4-4-12

 

[stagepuppy]

update on pushing the system...
E6400
FSB now at 400MHz, CPU at 3.2GHz
timing still at 4-4-4-12
RAM voltage at 2.2V
CPU voltage at 1.40V
MCH voltage at 1.30V, I think this was it, can't remember off hand.

Theyll run a minimun of 500Mhz CL5 @2.2v, might run alot higher on 2.4v (this is still 24/7 safe).

The Patriot 6400LL/LLK with black Black heat-spreaders are using Elpida chips (I have that worst memory (LL))
I can overclock 910-920 4-4-4-12 2.3xV but I want moore :x

Thats not so bad for those timings. Loose them up to 5-5-5-15 and see how far you get. Keep me posted.

5-5-5-15 1050 stable, Maybe will go higher, I dont test and dont care! I want 3-4-3-4 and thoose timings, but noo, stupid Patriot's
Btw, when I touch them on 900mhz cl4 2.2xV they are worm, not burning me, but very worm? What is the limit? Can they work like that?

(sorry for bad english)

 

[Gam3Ra]

wusy, are you shure about that?
2.45V is good for 24hours? Can I kill them? Where can I find info about the memory burning? I want to know what is the reason for killing, temperature or voltage (more voltage - more temp, but can it be killed by very much voltage and low temperatures?). I know only for the timings that they can't kill. :roll:
And no matter that the chips are Elpida, infineon, micron (...), they can work fine with 2.45V?

 

[rwaritsdario]

Theyre behaving exactly like Micron D9s, I highly doubt theyre Elpida. Got any confirmation on this?

 

[Gam3Ra]

No, but see this http://www.xtremesystems.org/forums/showthread.php?t=120839

:roll:

wusy Sorry, very bad english I have

 

[rwaritsdario]

Naah, theyre Micron D9GMH. Theyre behaving exactly like that and the guy was said that were Elpida doesnt have a clue...

 

[Gam3Ra]

Naah, theyre Micron D9GMH.

And do YOU have any confirmation on this?

 

[rwaritsdario]

The fact that theyre acting exactly like such and Elpida doesnt make modules that can reach 500Mhz.

I don't care if it using Elpida chip or Micron D9DQW. Why they're not still using Micron Fatbody? for economic reason?

The damn conclusion is Patriot PC2-6400-LLK is really sucks! I wish I got the older red one.

 

[Gam3Ra]

What are your results with that mem?

 

[bengkiam]

At 5.5.5.18, the max speed is 1050mhz, do u know how much voltage require to complete dual superpi 32m & memtest86? 2.5v!
For 4.4.4.12 it only stable at max 940mhz 2.4v.

o_o thats a lil voltage hugger! At what voltage do you run 24/7?

 

[bengkiam]

24/7 no oc at all... seems patriot had oced this memory from cl5 to cl4 themself +0.1v, normally ddr2-800 cl4 voltage is 2.1v (even Gskill HZ only 1.9v - D9GMH)

 

[rwaritsdario]

Probably it even isnt D9GMH...
Have you tested for 2.4v 5-5-5-15?

But only the Red Patriots 6400LL are with Micron D9DQW, mine is BLACK
Can enybody help me? Google don't wanna talk very much

No. I have asked to Indonesian Patriot distributor bout this LLK, they said mine (black spreader) is definitely Micron D9DQW (cycle time 3.75ns) and the older red one is D9DQT (cycle time 3ns) same which Mushkin used in their XP6400.

 

[Gam3Ra]

they said mine (black spreader) is definitely Micron D9DQW

ROFL :lol:
If they were D9DQW they will do 4-4-4-4 1000 with 2.1V-2.2V :twisted:
Mine is 1:1 like yours, they probably are Elpida or something more crapy

 

[bengkiam]

Here are the placement of several micron d9 chip that we know:

D9GKX(80nm,2.5ns)>D9GMH(80nm,3ns)>D9DQT(90nm,3ns)>D9DQW(90nm,3.75ns!!!)

Many calls D9DQT and D9DQW fatbody because their chip size are fat (92-Ball vs 60-Ball in GMH & GKX)

Yes the D9DQT can be oced to 1000mhz CL4 2.1v-2.2v but D9DQW could not. This things also happen to Corsair 6400C5 which also using D9DQW.

This things also happen to Corsair 6400C5 which also using D9DQW.

Or used to use, Corsair wouldnt be left behind on the 60-ball transition.

I have DDR2 800Mhz (check the specs in my sig), but OC'ed my chip, and maxed out the FSB at 370. Therefore my RAM was running at the 1:1 ratio of 740Mhz with timings of 4-4-4-12. I then used the 4:5 mem devider, and OC'ed my memory to 925Mhz. I had to loosen the timings to get this right to 5-5-5-15.

I ran PCMark05 and 3DMark06, and the results were slightly less. I need to figure out which option I use (ie. higher frequencies or lower latencies).

Are there any accurate benchmarks out there I can use to figure out what's my best bet here. Do you guys know off hand which setting I should go with? Thanks!
