lowering RAM timings = higher temp??

Hi all

Does lowering the RAM timings cause the memory to run hotter? I am trying to see how far I can push my Crucial pc2100 and having a lot of luck... just want to know if the timings effect temperature the same way that increasing the speed does.
 
Not even for itself? I mean, eventually the modules would overheat themselves, right? Why else would ram ship with heat spreaders etc?

heat spreaders are a fashion statement, unless youre really, really, really overvolting and overclocking your RAM, heat is NEVER an issue. to answer the question literally, yes lowering the timings will push the ram harder, so it will get a little hotter. however it wont make a difference for anything.
 
Well, I've had RAM get pretty hot on default settings. On my P3 system the RDRAM modules witht he heat spreaders have burnt my fingers before. How many people have burn scars from RAM here? :p

thats RDRAM. RDRAM just sucked :p
 
Very true, It was a Intel prototype mobo that was never fully released. one of the few that had RDram, that stuffs sitting in a server running in my garage now. i have like 3 of em.
 
If that is true, you guys just saved me $40. I was all set to walk down to BigFootComputers.com and buy some spreaders.

HEH

I seem to be able to run my Crucial PC2100 (266) at PC2700 (333) speeds at 2.5/2/2/5 and I don't have ANY stability issues. Pretty good, I think! I have now backed that down a bit, and I am experimenting with upping the FSB to OC the cpu next. So far I have it running at 18x155FSB=2789Mhz, which is a 389Mhz increase from stock. This is with stock cooling (plus Arctic Silver) and stock voltage etc. I am getting 27C idle and 40C under load with Prime95 running for about 1/2 hour. I ran 8 passes of Memtest and found now errors.

Wonder how far I can push this thing... The CPU stepping is 7 and revision is C1. Does that mean anything in terms of how far I can push this?

cant answer the CPU questions since I dont know P4's all that well, but as for the ram, make sure its 100% stable at those speeds, run http://www.memtest86.com for 6 or more runs and see if it finds anything. i had some crucial that OC'ed like that but when I ran memtest it'd get a few errors, they unfortunatly didnt go away when I removed the OC so I had to RMA the stick :( thats not saying itll happen to you, but im just saying, test the ram to make sure :)
 
Yes, as I said, I ran 8 passes of memtest and it found no errors.
Gonna go run some more. Will report back later.

Oh you bastard. I wish I could walk to Bigfoot Computers.com :\

I'd have to walk about 3300 km though.

i missed that heh

you dont need to run anymore, looks to be good.
 
is that a trick question? do you mean lower as in relax? or lower as in less time?

Hah.

Well if you do ever decide to take that long loooong stroll, make sure to triple check that they actually have the item you're looking for in stock. They've been frustratingly out of a few things the last couple times I've gone and forgot to (though for me it's 20 minutes on the subway and 10 minutes on the bus :D )

I wish they'd get some of those 120mm aluminum fans in stock... and the other thing that makes me wonder about this shop.. total lack of 1/2" ID watercooling components/parts/accessories :(

As in to make the ram FASTER. :) No trick question.
 
Ok, I got my FSB up to 167 before I got a blue screen in Prime95. This is pretty good, for 133 ram!!!!!! Now I wonder how to avoid that blue screen... more voltage?

I have everything back to stock speeds at the moment.
 
Heat is a serious issue for me an my ram.

I run my Panaflo L1A fans at 5-7v, and I overclock a lot too. My ram gets hot enough to cause discomfort when I touch it.
 
Ok, I tried upping the voltage on both the CPU and the RAM - no luck. Guess 167 is the limit for my RAM.

I will back it down to 160 or so and consider that good enough!
 
Doing 160 on ram rated for 133 is doing quite well. Consider yourself lucky, and maybe think about getting some newer ram.

Too bad Intel is trying to bring a new form of RDRAM back. :(

As for RAM, the heatspreaders are not purely cosmetic. They aren't heatsinks, they're spreaders. As I see it, you move the heat from the hot part of the chip to the other parts of the chip, keeping the chips a slightly cooler temperature. And yes, I have noticed a difference in performance with and without heatspreaders. I have a Mobile Duron with 512 megs of PNY crap, and with heatspreaders, I can get up to 2 - 2 - 2 - 11 at 2.7v. This is at stock speed, of course. I could never get under 2.5 with a higher clock or with lower voltage.
 
pc2100 isn't made much any more. A lot of the newer pc2100 I've seen is using 6ns (333mhz) or faster chips. Therefore, a lot of it is just rebadged pc2700.

Is there anyway to tell if that is the case with the sticks I have? Some marking on the chips or something?
 
yes, look at the markings on the chips. Some manufacturers leave the "ns" rating on the chips, and others you have to look up. Post everything on the chips and I'll let you know what they are rated for.

Ok on the chips:


0308 1-1
MT 46V32M8
TG -75C

2 sticks like that, and 2 like this:

0148 1-1
MT 46V16M8
TG -75B


All 4 of my sticks are the same Crucial model number, but I bought them 6 months or more apart and the last 2 are obviously a new revision. The older ones are single sided, and the new ones are double sided.

So can you discern anything from this? I sure can't!!!! ;)
 
yup, they're made by Micron technology and rated for PC2100 (133.333 mhz). They're 7.5ns chips. Being able to OC them to PC2700 levels is just dumb luck :).

The first two were made in early 2003, and the last 2 were made in late 2001.

NICE. Thanks! Would you mind sharing how you interpret these markings??
 
0308 (Year: 2003, Week: 08. So, these were made in the 8th week of 2003) 1-1
MT (Micron Technologies, they use MT. Most Chip man. use their full names) 46V32M8 (this has to do with how many chips, and it has 8 32meg chips)
TG -75C (the 75 stands for 7.5ns, 1000/7.5 = 133.333. That is what the chips are rated for)

you could also look them up at microntechnologies.com, some manufacturers like Samsung don't have many identifiable markings on their chips, you have to look them up on their site.
