C90 Compatibility questions

Hi,
I'm considering buying an Asus C90, but I have a few questions first:

Are all the LGA775 Cpu compatible with this laptop?

Is it compatible with Corsair PC-5300 memory in general? It would be a 2x1GB configuration.

Thanks in advance!

 

hey man !

Just got my c90 a few days ago... and i ordered a 1pcx2gb corsair (excaliberpc) as well... unfortunately i cant run from battery power. For me its not compatible....

But if you remained plugged in all the time, it works. Right now i just used 2pcsx1gb sticks to use both battery and ac power.

 

this is why i like quality check. mines works on battery and power. i just order everything on the list so it is compatible.

 

curiously though, einhander, did you try a single 2gb stick with ur c90 ? i believe you have a 2pc x 1gb RAM config. Most people do not report problems with this setup...

 

Einhander, I love that game for playstation. I own it.

Moving on to the OP's question.

Not all LGA775 CPU's will be compatible only because you need to buy with mindset that if the CPU has a title with Santa Rosa on it, it will not run with a laptop running a (Insert different title here) title on it. Also, you need to figure in that a motherboard with a maximum FSB of 1066 MHz but is configured to run LGA775, will not run a CPU that has a FSB of 1333 MHz.

Also, alot of people are having problems with compatiblity of RAM. One person will run Corsair just fine, but another with the exact same Corsair memory set-up will be having problems.

Personally, I ordered memory straight from the company I bought the barebones from. GenTech. I haven't recieved the C90 yet, but I expect it to be here in about 2-3 weeks.

EDIT: Only because I lack knowledge on the subject of the CPU, don't take my word for the different running titles. That's just something I'm kind of assuming. Let someone more knowledgeable than myself answer that question for you.

 

e6300,6400,6600,6700,x6800

 

I'm sure I read somewhere that the E4300 or E4400 would also be compatible? Why can't Asus release a list or something...

 

Einhander: Yes.

But as for the different titles. Do they extend with the E6XXX series? Like, Conroe to Conroe-L, or Prescott to Kentsfield? Or is that a completely different line of CPU's? The different Core titles is what I was talking about. Now I'm making it a question because I don't know.

 

The only thing I know is that they support a specific socket type, the LGA775, which has a wide range of CPU. Does that mean that most of them are supported?

 

The ones that einhander posted are the only supported 775 socket types by the C90S. Of which I quoted bellow.

Now, even if a motherboard supports LGA775 socket type, it might not support a specific Core type or even a wide band for the FSB. In which case the C90 only supports the Conroe core type. Which is why other's only support Kentsfield, or other Core types, which are mainly found in Desktops and not laptops. Being as the C90 is a desktop replacement, it carries a desktop CPU. Also, the motherboard found in the C90 will only support up to a 1066 MHz FSB, and there are other LGA775 Conroe CPU's that will go as far as 1333 MHz FSB.

That's about the limit of my knowledge. Ask more questions if you got them, I'll help with what I can.

 

corsair 2x1gb works, but the bios doesnt give enough power to run a 1x2gb stick

sad, and seems like corsairs power consumption is one of the few that are low enough to actually run

ive run through 380$ of ram already, and i can only return 140$ of it (a 1x2gb stick from newegg) cause my system took 3 weeks to ship while my ram took 3 days

 

Not sure i follow... Do you mean the ram speed no being able to go higher due to power requirementes??? Or do you mean about 1x2gb crashing??? Cause mine posta and works fine on standard mode its on battery mode that it crashes...

 

That much would seem obvious. If the 2GB stick required more voltage than is consistently delivered, there will be problems, potentially like the one you are having. I don't know why you put up with that though. Why keep a laptop or the RAM that doesn't work if you can't even unplug it?

 

That's one of the main reasons I stuck with having the dealer supply the RAM for me. That way I know the 3 GB will work regardless.

 

Don't you lose dual channel capabilities with mismatched sticks of RAM? I can't see in what scenarios 3GB of RAM will perform better than 2GB in dual channel mode.

 

sigh. I also ordered my 2gbx1pc RAM stick from the same dealer... ( but it still doesnt work ). So to all future c90 OWNERS : if u plan on ordering a 2gb+1gb config, ask ur reseller / dealer to immediately test it on battery power.... this is a very important precaution.

 

Unfortunately, I found that out after the fact that I ordered it. Which bothered me.

Pogitz, I noticed alot of people having trouble with the 3 gb config on battery power as well, but I had also noticed a majority of them ordered the ram aftermarket. You're the first case I've seen so far that has been straight from the reseller/dealer. That worries me since gentech already sent out the laptop. The only problem I have, is that it will take 3 weeks to get to me from gentech, and if I have to send it back..... Well, 3 more weeks kind of screws me over. Now I just have to pray and hope... damn.

 

hey whiteeightball !

Yeah. ordered mine from a reseller... however, they don't do extensive testing like gentech... ( from the forums, it seems like 90% of orders are from gentech. ) With gentech's experience on a LOT of c90's, plus the fact that they're going the extra mile to do extensive testing on ur unit, chances are ur c90's gonna be fine.

 

If there is a problem, they will take care of it without a hassle.

 

pogitz, Thanks for the info.

Forerunner, I realize that they'll take care of me, but I'm overseas right now so it takes half a month for anything I order to get to me, it's just a hassle really. If it is something that I can trouble shoot with them on the phone, that's great. If not.... not so great.

 

dont worry 3gb is still better than 2gb if you have it working even without dual channel. Dual channel is a very small performance boost that you will not notice in real life applications or use. Only a benchmark will show it.

Plus many dont know that there is a sutch thing as dual channel with 3gb of ram, its called asymmetric dual channel, its not as fast as regular dual channel but its very close. The c90 supports it because when I was using 3gb cpuz said I was running dual channel with my ram.

 

Oh. The more you know, right?

Thanks for the info Viscious. Now I just need my question answered over in the OS and Software section and we're in business once the barebones gets here.

A little Off Topic, but I got my box in from NewEgg today that has the software, OS, HD, and CPU in it, and there is this big gaping hole in the side of the box. Like it was punctured, there were packing peanuts falling out and everything. Sooo, now when the barebones gets here I get to find out if any damage happened to the HD and CPU while in transit from the states to over here in Lithuania.

 

A HD and CPU should be able to stand up to a good bit of wear and tear I would think. Stuff like that is more sensitive to electric discharge ect than a good bashing from the ogers that work for shipping companies.

 

Assuming the parts were retail and individually boxed, it shouldn't be a problem. The most fragile item would be the HDD, due to its platters, if it was bumped around too violently.
