louis is looking for a new 2 x 2gb kit

[LOUISSSSS]

okay so i'll leave tRFC = 54 and bump my NB/MCH Voltage by 1 or 2 notches. what program can i use to get a (ballpark) reading of the NB(MCH) voltage?

and yes, i had reformatting/reinstalling windows planned bc my last sticks of crucial ballistix corrupted my OS install
planning to install XP w/ Sp3

Leave tRFC there, or even looser for now, till you determine your desired speed is stable.

Then you can tighten it up somewhat, though considering how minuscule of a performance drop a higher tRFC is, it doesn't matter much.

I'd say try dropping to 5-5-4 or 5-5-3 if you can...some people have success with a lower tRP.

Just as an example, with 2x2 of my Mushkin, i could do DDR2-900 5-4-3-12 stably...not really any higher though sadly.

i'm dont have much of a desire to tighten timings for marginal gains of performance. keep in mind i'm coming from ballistix DOA/RMA galore so i just want a stable system so i can stop using my slow pentium M laptop

my goal would be:

CPU: Q6600 8 x 400 = 3.2ghz @ 1.275v in Bios
RAM: G.Skill 2.5 x 400 = 1000mhz @ 5-5-5-15 @ 2.0v [or 2.1v]
NB: 1 or 2 bumps from default (still looking for a program that can read northbridge voltage, the DS3P BIOS only tells *default*+0.05, +0.10...etc

 

[LOUISSSSS]

update: just got my windows xp SP3 installed and running OCCT, one notice: CPU-Z, SPD tab, why does MAX Bandwidth say PC2-6400 (400mhz)? i know i've read this somewhere else before too...

 

[LOUISSSSS]

update: just installed both DIMMs and ran OCCT v2.0 beta RAM for 2 hours. PASS.

settings tested: 8 x 400mhz CPU (3200mhz). 2.5 x 400 RAM (1000mhz) 5-5-5-15 54tRFC @ 2.1v.
NB +0.100v


question: what program can read NB/MCH voltage?

That's because your mem is nothing else but factory oced PC-6400 mem. That's not unusual. JEDEC?s std for DDR2 mem goes up to PC-6400. Anything else beyond that is considered as factory oced PC-6400.

I?m using 2 pairs of G.Skill F2-8500PHU2-2GBHZ. One of them is an older rev and its SPD profile is set at PC-6400. The other one has an SPD profile for PC-8500 which is not a JEDEC std. There?s nothing to worry about.

Makes sense.

That's true. I guess I'm just a tweaker.

None that I know about, although the Gigabyte software might. I never even installed it, so I can't say. Not that it matters much. It should only require a one "notch" bump, and depending on the motherboard, doesn't always require that, unless trying to overclock the RAM, also. It's another of those things where YMMV, like most other things concerning overclocking.

i have mine bumped 4 notches i think.. MCB/NB +0.100

they go in increments of +0.025, +0.05, +0.075, +0.100...etcetc

is that bad? lol i had it at that setting when i was trying to get 4 x 1gb of Ballistix to work

 

[LOUISSSSS]

update:
Q6600: 8 x 400 = 3.2ghz @ 1.232 (load, cpu-z)
DDR2 1000: 2.5 x 400 = 1000mhz 5-5-5-15 tRFC: 54 @ 2.0v
Misc Voltages: FSB: +1 notch, MCH/NB: +1 notch (+0.05), PCI-E: default

XP SP3:
pass:
- OCCT RAM (2h)
- OCCT CPU (2h)
- P95 v25.6 (24h)
- 2 x SMP F@H (24-48h so far)

Good stuff

Let's hope your memory luck has taken a good turn

 

[LOUISSSSS]

yea and i'm still in the middle of getting 2 new crucial ballistix.. they said it might be a better idea to get something like 16___ ram =\ forgot what the rma guy said.. less dense modules?
so thats what they're sending me

 

[n7]

They're likely sending you the new ICs.

The stuff everyone has been screaming about being worse for OCing (it is).

Might be better for reliability though...hard to say.

 

[LOUISSSSS]

i don't know, i'm probably just going to sell them as brand new since they're in the original package

I've become a really big fan of A-Data over the past few months. It seems their performance is pretty much on par with Crucial but without the high failure rates.

I just recently sold my 2 X 1 GB kit and ordered the 2 X 2 GB kit instead. Here is a link they shortly sold out after I bought them.
