Has anyone upgraded their IQ524 or IQ526 to 8GB of ram???????? Techsupport THINKS it's possible ,however the two reps I spoke to were not sure.

I want to be sure that it can be done before I attempt it.

The IQ524 and IQ526 both use the newer Pegatron IMIMV-CF (Maureen) motherboard that uses the newer Intel GM45 chipset.

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01635715&lc=en&dlc=en&cc=us⟨=en&product=3875698

Stated directly from the HP documentation for both systems (bold/underlined for emphasis);

  • Dual channel memory architecture
  • Two DDR2 SO-DIMM (200-pin) sockets
  • Supported SO-DIMM types:
    • PC2-5300 (DDR2-667 MHz)
    • PC2-6400 (DDR2-800 MHz)
  • Non-ECC memory only, unbuffered
  • Supports 4GB DDR2 SO-DIMMs
  • Supports installation of up to 8 GB RAM
    • All 4.0 GB is addressable on 64-bit operating PCs
    • Approximately 3.2 GB is addressable on 32-bit operating PCs

 The product manual shows how to replace it;

So what you need is two 4gb DDR2-800 mhz SO-DIMM (will give better performance over the 667 modules) memory modules.  They're pretty expensive right now still though.

hmmm. Why in the 500 series and NOT the 800?!

Thanks Brentil,

Reason why I was asking was I was afraid that the IQ526 would not handle the extra heat . So I would like to know that somebody has actually attempted this and all is well.

I checked in with NewEgg, and the cost of the 8GB DDR800 Ram is up around $370 plus shipping for sometimes unreliable Corsair memory in matched pairs (4GB + 4GB) for dual channel 200 pin SODIMMs, and $515 with Free Shipping for the Crucial branded RAM. Both of these run at CAS 6, and with 1066+ DDR3 RAM gaining popularity, you might want to keep an eye on the availability of this flavor of RAM to be sure they don't drop it from the market in the near future.
You can go to their website to check it out here if you are interested.

I dunno, but that is why I bought the 526, for the PM45 chipset, and the TV tuner.

Did you really win yours?

BTW, the P9500 CPU is still running just fine @2.53GhZ in here with the 1066 FSB in my IQ526, thanks for (not) asking...Wink

Maybe next year they will have an X38 chipset in there like the ASUS W90 I almost bought before I decided on this HP TS. I understand that there are a LOT of problems with that machine...

Whoops, did I say PM45 chipset? I meant the more robust GM45 chipset, still a notebook level part, usually found in business oriented laptops, but no slouch, either. I'm much happier with the performance of my machine with the 25W P9500 in there, and I'm hoping it allows me more power supply headroom for the 9600GT I am starting to look for. If I can find a 9800GS or GT, I may go for that if it doesn't outrun (or smoke) the power brick.

Why would you assume that upgrading to 8GB from 4GB of RAM would increase the thermal removal efficiency of this (or any) machine? You are still talking about using only 2 DIMMS. If there is any power difference, it's miniscule at best. I'm sure that HP/Pegatron has worked in tolerances so that RAM from different manufacturers with varying power requrements could be used in the event that due to shortages or acts of God, the contract vendors could be substituted for other DIMMS with different power handling characteristics.
Just my 2 cents...

From my experience with DIMMs in laptops, they do run hotter when each module is more than 2GB. I was thinking that the TOUCHSMART may be more sensitive to HEAT.

The TS is more open inside than most laptops and due to the up/down configuration is never laying on a surface which acts as an insulator keeping heat inside.  They'll make more heat but it's probably negligible to the overall heat of the system.  The HP website would probably not mention the ability to upgrade to 8gb of ram as well if the thermal capacity wasn't there.

Just out of curiosity, I went to go see if I could find some 4GB RAM on NewEgg to see if there were any laptop and desktop modules for sale. I wanted to see if there was a higher wattage requirement due to the higher density in each chip. I found 1 set of 4GB Dual Channel RAM by Kingston, there were no reviews, it was $415 per pair to make 8GB total, and they were out of stock. That was for the consumer level desktop.
There are 4 offerings of 4GB RAM for the laptop on NewEgg, and 3 matched 2x4GB dual channel sets, probably the largest inventory in one place that you will see for consumer level PC parts. No heat spreaders here, they might not fit every laptop, so they are "naked".
They do stock and sell 4 and 8GB modules for servers, and as a matter of observation, only 3 of 9 of the individual sticks I looked at had very basic sheet metal and clip heat spreaders, all were either ECC, registered, or buffered,(won't work in most consumer mobo's) and most ran at DDR2 667. I really don't think that ANYONE but the enterprise IT guys and the manufacturers have much experience with the characteristics of 4GB RAM modules, so they might be the only ones to ask to find the answers to the question you have. I still tend to believe that due to the high cost and low demand for this RAM for the laptop variety, coupled with the advent of DDR3 1066 and 1200 modules, if you want it, you better get it now.
Hope this helps,
Dave

This Business or "Enterprise IT guy" moniker fits you, doesn't it, Brentil? I'm upping from a 9300M GS to a 23W 9600M GT, I can't find the specs on the 9300M's power requirements, but even if it is 5W more with the 9600M GT, which is in some of the custom ordered 500's and in the IQ816 pre-builts, the RAM is not going to generate 5W more heat by going from 2GB per stick to 4GB, is it? We're not talking about overclocked RAM here either, the stock 667 and 800 speeds are industry standards with no thermal problems to speak of. As you said, the upright position of the PC lends itself to better cooling efficiency, which is a plus over a laptop design.
We are beating a dead horse here, the RAM in that flavor probably won't be for sale in 90-120 days, so if you gotta have it, you better go for it now, because if they don't sell 'em, they won't make any more.

I currently have 8gb of RAM installed in my IQ526. Works great and doesn't generate any more heat than it did before. I'm upgrading from the T6600 CPU to the P9500 tonight. I'm going to post the updates on that as soon as I get it up and running. Feel free to ask any questions you might have and I'll be more than glad to give you any information I can.

Ok, I've done the installation and reboot as well as testing. You can find more information on it here: http://www.touchsmartdevzone.com/forum/thread/598/Any-succesfuly-CPU-or-MXM-u...

Maybe... and a Computer Engineer too.
