2.4C @ 3.0 GHz maximum overclock on IC7 w/ Zalman 7000. Did I get a runt or what?

[FPSguy]

My Antec TrueBlue 480 is awesome.

My Kingston HyperX PC3500 (which exhibits the Winbond CH-5 characteristics on my ABit IS7 -- i.e., trouble with FSB > 250 with 5:4 memory ratio) sucks though. :|

Yeah. Although if you check Enermax's website, their PSU's are (IMO) unparalleled for P4's. 350W has 26A, 450W has 33A and the EG-651 has 36A.

What voltages do you get on your TrueBlue480W?

I get (on my 430W):

+12V 11.61-11.73V
+5V 4.87-4.89V
+3.3V 3.14-3.22V

^ that sucks about the HyperX.

Does this problem exist with BH-5 memory? (I will test this later with my single stick of BH5 but I'm too lazy to at the moment ) . If BH5 is exempt from this problem then I can simply trade my single CH5 stick (which is supposed to be a slightly better o/cer anyway) for a BH5 stick to have a pair.

I wonder if that probelm will be with the IC7 mobo and hyper x 3500...I was thinking about getting some, but now I may just get the Geil golden dragons!!!!

My 430watt enermax right now at near idle....

+3.3v = 3.33v
+5v = 4.98v
+12v = 11.94v

load

+3.3v = 3.31v
+5v = 4.97
+12v = 11.83v

My 430watt is low now and may need a better power supply when I get my 2.6c and go for 3.5ghz, but I will cross that bridge when I get there....

If that HyperX 3500 has Winbond CH5 chips then STAY away! I've now confirmed that on my board (just like in the Abit forms thread) Winbond CH5 chips don't let you boot at any FSB above 250 MHz. The BH5 chips, however boot fine (running at 270MHz FSB right now with a single BH5 stick).

Hehe, I'm glad you got the board running great now.

The memory timings are very picky when ocing, as you already found out. Wish I saw this thread earlier, so I could have helped out. Very nice overclock by the way. And as for the bios, I left 1.7 on there for ya when I shipped it out.

Have fun!

You're the man, Thor!

Yeah, 3.2 GHz is pretty sweet, but I just know this chip has more in it with a more stable PSU. I'll post my results tomorrow with an Enermax 430W when I get it... stay tuned!

 

[Duvie]

So how am I going to know if it is BH5 or CH5 chips??? If I buy from someone can I have them just look at some marking on the chips???

Do you know if the Geil Dragons use winbond chips??? I may get (2) 512mb Dragon pc3500 sticks for 225.00

If you guys are looking for some good memory, Newegg has:

Mushkin 1GB PC 3500 Level 2 Dual Pack (2x512MB) CAS2-2-2 Black, Part# 991098 - Retail
Specifications:

Well, I got the Enermax this morning and the results are disappointing (from an overclocking point of view).

The Enermax 430W PSU has tightened up my voltages a bit:

here are the lowest voltages recorded:

+12V 11.80 - 11.92V
+5V 4.92 - 5.00V
+3.3V 3.23 - 3.44V

As you can see, all of the voltages are much closer to what they "should" be, and of particular note is the +12V rail, which is pretty good. This is at 3.2 GHz.

However, there is no significant improvement to my overclock. Prime still fails instantly at 3.36 GHz, and fails after 2-5 minutes at 2.26 GHz (instead of failing right away on the Antec), regardless of voltage (I've gone up to 1.65V actual.. highest I'm going to do, also).

So, it looks like I'm at 3.2 GHz to stay with full prime stability (although if I really wanted, it is perfectly Windows stable at 3.3 GHz).

So, despite the significant difference in Amperage between the Enermax and the Antec (33A on the 12V rail for Enermax, 20A for Antec), there is an inconsequential improvement in stability. Perhaps it buys an extra 50-75MHz above 3 GHz.

I'm still happy I got the Enermax, however. Now, to get that other stick of BH5 memory .

I am not in front of the computer with the TrueBlue right now, but I can tell you that I had a "Real PC Power" 450 watt power supply and the voltages were all over the place. With the Antec "True" power supply, supposedly there is feedback technology that keeps the voltages almost right on, and I can verify that the voltages hardly differ at all from 12, 5, and 3.3.

I have not seen reports of the ABit boards having similar problems with BH-5 chips. I need to replace my HyperX DIMMs with something that has BH-5 chips!
