1800+ DLT3C problem

[rrayden]

Hi everyone. I've been reading alot on this forum and so I decided to buy myself one of these bad boys.

It's a 1800+ DLT3C JIXIB 0336 unlocked. I heard it is one of the best overclockers but I have problems doing that. I have an Epox 8RDA3I mobo with a cheap WinPower 350W PSU and a TT Smart&Silent Volcano 9 with it's standard alluminium heatsink. My RAM is 256MB PC3200 A-Data and it does about 215 FSB max.

So here is the problem. First of all on stock 1.5V it doesn't hit 2Ghz as almost everyone else did. It requires 1.55V. Then moving on to 2100 it requires as much as 1.675 to be Prime stable. That seems a little too much. It also gets pretty hot at that point: 50C in full load. At 2150MHz it requires 1.7V and gets hot as hell with the fan at over 4000rpm :(

My voltages seem pretty ok: 11.8V at 12V line and 5.1V at 5V line. I also did some 10 hour "burn in" at 1.8V. It seems like it helped a little, I don't know... So is it heat the only problem i'm facing? My room temp. is about 26C and also the case is very small.

I am expecting alot more out of this chip...
Any advice is appreciated.

Hey there rrayden,

A few things. I do not have the same chip as you, but it is very similar, and yours will go a lot higher than mine at stock voltage. I can barely hit 1.8 on stock voltage. I now run 2400mhz @ 1.825 volts. Anyway, I'm not sure if you have anything to worry about.

On the temps issue, when mine hits about 50 celcius, it becomes unstable. Even though that temp is WELL within the chips limits, it runs MUCH better when it is cooler. The Volcano might need to be upgraded, if you are looking for better performance.

Sorry for lack of hard facts, but I figured my opinion was at least something to consider. Good luck....and where the HECK did you get that chip?!?!?!?! I WANT ONE!

I have the 1800 JIUHB DLT3C also. My temp is 58 degrees under load. I don't think you have anything to worry about your chip. The temperature limit set by AMD deteremines the temp where hardware damage (to CPU or mobo) will happen. I don't think it deteremines that the chip will run stable at that temp. If it is prime95 stable, you have nothing to worry about.

Well I am from Romania and here in Bucharest you can still find some of these chips. Not exactly the one that I found, but there are plenty of DLT3C TIXIB 0351's. Dunno how they perform though.:-/

So you're saying it's not a problem not hitting 2GHz on 1.5V. Then I guess the problem is only in my cooling system. Also I am curious about one thing. Why is it that people don't usually go at their max FSB? I thought this was recommended. But I see people who can hit 210-215 FSB and prefer to stay at only 200... Will I get more performance if I'd stick to 200 too?

There are "NO" chips that will perform identically. Even with the same stepping code and week, 1 chip can still overclock higher than the other. Don't forget that when you overclock your CPU base on the FSB, that is also very dependent on the overclocking capability of your mobo (chipset) and the memory. The most important thing is that it must run stable. If the temperature is under 75 degrees (I think. Go check with AMD website), there should not be hardware damage. But like I said before, high temperature may cause instability.

I think durons do a lot better than recent dlt3c chips. My 1.4 does 2.1Ghz on less than default voltage, 1.45, but it is only completely stable at 2.05Ghz with 1.45 volts.

Those Durons overclock pretty well too, but I don't think they have L2 cache.

easy to enable cache , just fill a pit .. I have a 0329 Miuhb 1.8 that does 2400 mhz with 1.90v . Not as good as most dltc "b" 's (under week 0335) but decent .. cheaper too ..
