Having some fun with 4400+......

[Smokey21]

Sup guys, been playing with my 4400+ a bit more today.

Ram seems to max out at 220. Ive tryed 3-4-4-8 super pi would fail and i didn't wanna increase DRAM much. I can't seem to find chipset voltage on this Asus.

Anyways, so far iam at 11x227 with 333 divider, with only 1.35Vcore, which gives me basically 2.5ghz. Temps are 48C load running Super PI 32mb on each core.



Pics and benchies 2moro.

You dont need increase chipset voltage for anything important on nf4!

Chipset voltage affects stability of hyper transport alone - which really affect performance, as at minimuim voltage it should always be stable at ~600mhz or lower (3x200mhz at stock fsb) which is more than enough.

Memcontroler is on cpu, so its cpu voltage you increase.

So your ram is currently at ~189mhz?

Stick it upto 240fsb and 9:10 (216 ram), that should get upto 2.6 with some more voltage

No idea why your timings are so slow.. make sure HTx is 2x or 3x - it really makes no difference having it higher (and saves you from needing the chipset votlage up - which gets hot enough already with the crappy stock coolers..). that should help it be stable with faster timings/higher ram/fsb..


1.35v for 2.5ghz - thats amazing! but I suppose for the price of the chip youd expect it to do that so easly. Stick it upto 1.65! I want to know how far it goes!!!

NF4 chipsets run pretty hot. Don't increase the voltage unless you are using the Swiftech I showed you.

I run my LDT at 4X and my FSB at 249MHz, so RAM is 498MHz with 2.5-3-3-6 timings. This is my 24/7 aircooled setting running two instances of SETI.

Running 2GB of RAM is costing you performance big time. But hey, you need it, right?

You really don't need that much RAM. I'll bet with the divider your bandwidth is terrible. Have you checked it with Sandra?

Still, at 2.5GHz that thing is a crunching monster!

Still preaching? the fact that its not going faster than 3-4-4-8 at a max of 220mhz cannot be caused by the fact he is probably running 4x512mb sticks unless he has got it at 1T which would probably make sense.

My ram wont be far off yours, 2gb @ 228mhz 2-2-2-7 2T. If I swap over two TCCD sticks with my brothers so I have 4x bh-5 it then goes upto 250mhz @ 2-3-3-7 2T timings. Just waiting for amd to fix there mem controlers before 1T.. thats the only performance hit.


What advantage does having LDT at 4x give you? none.

Like so many of your other posts this one is almost 100% wrong.

1) 1T is they only way to run an A64. 2T kills your bandwidth.

2) 249MHz is my 24/7 speed. I can run much higher.

3) A higher HT (LDTxFSBx2) makes a huge difference in some things and almost no difference in others. Just depends on what you are running.

There is nothing wrong with AMD's memory controllers. Some people do not consider speaking the truth preaching, just attempting to fight ignorance, a nearly impossible task since there is so much of it. My question for you is, why do you fight so hard to be a part of that ignorance? Where is the payoff for you? It is common knowledge that less RAM overclocks better than more, especially on AMD64's.

You need another group hug???

Here you go!

Feel better?

[Merlin4458]

Il take a hug if there going free tbh.

Get yourself some nice TCCD ram. My pair of Geil Ultra-X could do DDR640-2.5-3-3-7 at 2.7V which gives me a lot of headroom when overclocking.

But 2.5Ghz is pretty good already.

Well it wouldn't do that on an X2, but it would be much better than what he's using now. 2GB just isn't going to overclock well. That's the price you pay for having a lot of RAM. Hope he actually uses it, however unlikely that is.

Heck yeah, 2.5 GHz twin DC A64s? Are you kidding me?

HEY SMOKEY....Run SETI for a couple of hours and see how many work units it completes! I'd like to compare your settings to my 4200+.

Neither of us are wrong.

I have never said 2T is faster, or that it makes no difference, but that I need 2gb of ram, and I assume that other people that have it would also need it, or they would not have bought it. The slightly lower bandwidth of 2T is made up for buy the fact I need 2gb and it would be slower to have the HDD trashing constantly AND the fact it is overclocked slightly to make up the differnce. I have took a stick out and tested and it was noticable.

BTW crucial are selling 1gb sticks now (and have for a while). When using 2 of these in my other DFI NF4 it is as expected - perfectly fine at 1T. I have tested both (almost identical) systems and theere is no noticable differnce at 2T for the ram-hungry programs I am using.

"nothing wrong with memory controlers" - well there clearly is if they are limiting the ram to below what it is capable of. There has always been the same problem with every chipset, noone expects 4 sticks to run as good as one or two but it is still a problem - AMD consider it a problem - becuase they are trying to fix it!

As for the ram speeds above, that was on stock voltage and so will go much faster when pushed and be 24/7 stable.

The inability of nf4 chipset at stock cooling, to run above 600mhz prevents me testing how much differnce it makes. Im running at 550mhz which is the closest I can get at this fsb. Above 600mhz is not stable on both nf4 boards I have, and stabilty > performance.

No thanks, the ram is fine.

A64's really don't need extra bandwith, as plenty of benchies show.

The timmings are 2-3-3-6 i run. Iam now at 11x230 for 2530mhz, same Vcore.

|SilentDeath| 1.65vcore is impossible on an X2, without phase. The heat gets to much over 1.5, my temps are already 48C, iam going to stay under 55c, so probly 1.4 limit, but at the mo i don't need the volts.

Had TCCD, had VX, to much hassle with high volts, and crap with UTT based ram, and im not botherd about getting a high HTT with 1;1, it's been proven not to matter, so please, shaddap about the ram.

Glad to know about the chipset, i was just expecting it to be same as my NF3.

Is that on air or water, and whats stock voltage for these chips?

[Smokey21]

X90c, in sig. Still on 1.350Volts, stock is 1.3. Currently just about to do 32mb PI at 2588mhz!

[SilentDeath]

X90c not in sig

Im really tempted to upgrade to a X2 now (or in the future). Water should be good for ~1.65v with these chips. I can see a LOT of them breaking 3ghz based on your speeds

[Smokey21]

1.65v, would more than likely be far to hot for Water. 1.55 is to hot for water.

I haven't seen many that can do the clocks iam getting at these voltages, might be just a lucky chip(s).

Most will do 2.6 i think max on air. We'll have to see what i get.

[SilentDeath]

X2's power output would probably hit 150w maybe 200w (a guess).

With water I would guess 60c load temps for cpu, at that voltage, when using a 120.3 rad, and a decent block with high flow rate - again a guess based on prescott temps.

[Smokey21]

60C load temps is to high for best overclocking results, especially on water, that would major deacrease your clocks.

You can't pump volts into these.
