Using 4 memory slots wile overclocking?

Anyone ever run into any problems overclocking wile having all 4 memory slots full in duel channel? I have heard it can't be done

Nope.
I have four sticks of Kingmax PC4000 ram, and they all run in dual-channel perfectly. They system runs quite stable at 245Mhz, but at 250Mhz (which is what the memory's rated at) it will reboot every now and then in games. I can't confirm whether it's the ram or not (probably not) but I hardly think it's an issue with 4 DIMMs being used.

MS-7003 Memory slots

Fresh post on this problem:
My MS-7003 mobo had just come back from being RMAed
The problem i had at first was that i kept getting bsod errors when my 256mb micron memory was plugged into slot 2 on my mobo. so i ran MemTest86 V3.2 and got errors on test 5. The memory is fine when tested in slot 1.
I still have this problem with slot 2 even after RMA. Only now i get errors in test 5 & 8
Is this just a problem with not having any memory in slot 1? I only have one stick of 256 so i cannot test without buying more ram (which i can't afford atm) But in my mind the ram should work on it's own in either slot anyway!
Or is slot 2 still duff? The mobo ram and cpu came as a bundle so should be compatible.
My concern is when i come to use both memory slots at the same time. i.e i upgrade with another 256 ram will the memory in slot 2 cause errors?
All help appreciated.

Hi Harib0,
I'm running the MS-7003 mobo in my media centre PC.
Stumbled across your post while looking for BIOS flashes for the board, and thought I'd do some testing.
Have been running a P4 1.8A (512K Northwood) and 256MB micron DDR333 (2.5-3-3-8) in slot 1. Onboard graphics and sound and is running fine for me.
Tried running memtest-86 with this module in slot1 and slot2, no errors.
Tried 2 x 256MB Corsair VS DDR400 (3-3-4-8), slot1 and slot2 individually and both together, no errors.
Tried 2 x 512MB Corsair VS DDR400 (3-3-4-8), slot1 and slot2 individually and both together, no errors.
Tried 2 x 512MB Crucial (micron) Ballistix DDR400 (2-2-2-6), slot1 and slot2 individually and both together, no errors.
So the memory works fine on my board. Got my board from an OEM source as well it has BIOS version 1.0b31 which I assume is a beta BIOS. If you are using a different BIOS I'd really appreciate it if you could save it and send it to me before you RMA the board. If you install msi's live update 3 you can do this in windows with the following utility:
C:\Program Files\MSI\Live Update 3\FlashUty\Award\WinFlash.exe
I think you could be having one of 2 problems.
1. Bad BIOS that needs updating, although the update may not be available. I can check your BIOS on my system if you send it to me and perhaps my BIOS will resolve your problem.
2. Motherboard does not support your CPU. Again a BIOS update could solve this one but I wouldn't hold your breath for MSI to release one. This is an interesting link where MSI clearly state that "Pentium 4 Prescott (Celeron) - 2.8G - 533 - 21 - NO" does not work. MSI seem to be using a BIOS v1.1 and a lot of the Prescott CPU's seem to be incompatible.
http://www.msi.com.tw/program/products/mainboard/mbd/pro_mbd_cpu_support_detail.php?UID=537&kind=1
I’ve got a P4 3.0 I could test in the board but it’s a 512K 800FSB Northwood so I doubt there will be any problems. MSI’s site says the board works fine with 3.0 Northwood’s and Prescott’s.
Hope this is of some help and you get to keep the board cos the 9100 IGP is the best integrated graphics you can get.

Can i use 2gb memory in one slot in my 2006 Mac mini as the 2 slots of 1gb only reports only 1gb memory, both memory work ok in the one slot

Can I use 2gb memory in one slot in my 2006 Mac mini as the 2 slots of 1gb only reports as 1gb memory, both memory work ok in the one slot as I have swapped them over

To my knowledge 1GB modules are the max. size for the 2006 Mini.
2GB modules are not recognized/useable.

Is it possible to use the Memory Stick Pro from Sony in the SDXC slot on the MacBook Pro?

How could anyone "take it wrong"? Anyone can see at a glance that you're raging mad, shouting at the top of your lungs and ignoring the terms of use you agreed to abide by in posting here, all because you haven't read the guide that came with your computer and you're trying to make it do something it can't.

Powerbook Lower Memory Slot Issue, what are my options?

Hi there,
I have a Powerbook G4 1.5ghz that I purchased in October of 2004. I had no problems with it until after upgrading the RAM to 2 x 512mb chips and then installing Tiger which resulted in me later notcing the missing RAM and learning about the lower memory slot failure issue.
I find that sometimes if I remove the RAM and try and power it up and then replace the RAM again that the lower slot ocassionaly does come back. Trouble is though that the machine will either crash or I loose the other RAM slot when I have to shut it down. It seems to be so intermittent this way and I'm tired of constantly removing the RAM to fiddle about with it.
My serial number begins W8441, so it isn't covered by the returns programe. I would call Apple Support, but I am put off by a £35 charge just to have them discuss and diagnose the problem.
I'm in the UK and as I don't have Applecare and I'm not elgiable for the returns programe can anyone tell me what they charge for a logic board replacment? Looking at what they charge in the US, it's not cheap.
I use my Powebook for Final Cut Pro, DVD Studio Pro, After Effects mainly and I had been alright with 1gig when it was working.
I'm really trying to decide what the best thing to do is....
- Do I pay for the logic board replacement, which I'm not really sure I can afford right now, or to be without my machine... especially as I have read that it can just fail again.
- Should I just buy a 1gig stick for the upper slot and try and sell my old RAM, as that would be cheaper than getting the logic board replaced?
It's a real shame that Apple doesn't seem to want to ackowledge that this effects other users as I'd been so impressed with everything about Apple up until now.
Thanks for any advice.

(Browse down for findings and questions).
The notorious lower-memory-slot-bug has hit my finally too... I never believed it until now (and I've immediately signed the petition).
I am outside warranty and I never bought Applecare either.
Also my powerbook, a very dear machine to me, is a less common type to have this problem: a 1 GHz G4 15" FireWire 800 OS 10.3.9 type. Funny enough my older powerbook ( a G3 Bronze) is still running strong with no problems whatsoever.
My G4 15" also has the "white spots" problem and a dead superdrive... I cannot believe how many hardware problems I'm having with this machine in comparison to all my older macs - even my sluggish powerMac 7200/90 never gave me this many headaches...
Alright, I'll stop complaining for now.
I've been able to browse the internet on this and found the following statements:
The lower memory slot gets "fried" because of a OS 10.3.9 upgrade,
or possibly due to overheating when the powerbook is put on the users' lap,
or possibly due to picking the powerbook up by the corners so the metal gets bent.
+ I have only seen one case where someone's UPPER memory slot was defective.
The solution to this problem (replacing the logic board) didn't seem to be definate in many cases so I'm reluctant to try this myself (and I have very little money). The alternative (replacing the upper slot memory with a bigger type of RAM) seems a bit scary to me,
because I wonder:
-will the upper memory slot RAM get "fried" eventually as well after a while?
-do you need to have something installed in the lower slot or is it possible to just install one RAM card only?
-are there more people with a 1 GHz PB that have this problem? It seems it's mostly people with a 1,67 GHz that have been bitten by this bug and maybe that's why Apple decided to give the majority a free repair. I am not sure whether that is a common policy, I am part of the minority it seems.
As a solutions someone posted on a board that we should all buy KTA-PBG4333/1G RAM, but here in Dutch stores it is said this memory is only compatible with 17" powerbooks....
Does anyone know if it is suitable for 15" as well??

Memory slot utility

Hi everyone
I have just upgraded my mac pro early 2009 with an ATI 5870 and an extra 1gig of ddr3 ram.
All seems to be fine no problems all the ram checks out ok and is working but this utility keeps telling me everytime I boot up or log out and into another profile that the memory modules are installed in the correct slots which is really nice to know but does it have to tell me this every time as once is enough.
I have tried moving the memory modules around as slots 1 2 3 had the base ram installed at the factory I then added the extra 1 gig in the 4th slot and started getting the message as stated above. So I swapped the ram around with one of the base ram sticks and put one of them in the 4th slot still the same but when you remove the ram from slot 4 and boot up with 3gig of ram its all happy again.
So I then placed the ram in slot 4 3 and 2 leaving the 1st slot empty and the utility tells me it is the wrong configuration which is fine as thats expected as it will not give optimised preformance i just wanted to see its reaction.
I have phoned apple and they gave me a number for a local shop and the guy there said he has had this happen as well just make sure software and firmware are up to date and it should clear which of course they are and I have double checked.
So for now I went into system on mac HD and then into core services and removed the memory slot utility and placed it somewhere else for safe keeping and it has stopped now but thats because it can't use the utility.
I am stumped I can't see this being hardware it seems it could be software or a bug not sure either way I am covered under warranty but I just want to get to the bottom of this other people have reported this on these forums but not mentioned how they got on.
My next step is to reinstall lion I have my old osx leopard cd's also and then I can reinstall everything else from scratch but this seems extreeme
If anyone has any ideas I would be really gratefull
Kind Regards
Martin

Thanks for the replies and the suggestions much appreciated for now I have disabled the memory slot utility as I know the memory is installed correctly so I don't need it.
I went into the finder then into systems and then core services and removed the memory slot utility which is no problem all fixed the only thing that does concern me is if it is a problem that needs addressing because if I need a new processor board I would rather apple pay for it while I am with applecare as those babies cant be cheap.
My applecare service expires next september so I will keep an eye on things for now.
I have done some more checks my ram is fine no problems my system checks out ok and all is running fine as it has for the past two years since I bought my mac pro.
All my ram is apple certified ram and they are all equal memory modules 1gig in size each.
Memory can be added to slots 1 2 3 no messages but any ram added to slot 4 and it tells me the memory modules are installed correctly which really warms my heart but just don't tell me this every time I boot up and log in and out it tends to get on your nerves after a while.
Also if we do something that is not correct like put memory in slot 4 3 2 leaving slot 1 empty it then gives you a longer message telling you its all wrong and to swap them around which is fine as I did that on purpose just to see what would happen.
So do you think I am worrying to much and I should just chill out on this I found my fix just take the memory slot utility out of core services and it is all fine or like X423424X said enabling root though I went for the safe option and just removed the memory utility.
I know I am not alone I have searched the web and on this forum and there are others out there and everyone has different solutions the guy I spoke to at my local apple authorised reseller said he had the same thing happen but it was his firmware but that is not the case for me and others as that is all up to date and my software is also current.
Do you think its a hardware issue or software is there cause for concern as these things are not cheap.
Again thanks for your suggestions and comments its appreciated if anyone does find out what this is please let me know as it is playing on my mind I am one of these people who has to find the solution or cause I can't leave things be.
kind regards
Martin

Memory slots on D7-6100 will not pop up

Trying to re-install memory after repairs on my D7-6185. Went down to shell for repairs Have double/triple checked rebuild.

Memory slots will not pop up to all install of memory cards. Nothing is blocking them physically. At the point of pulling out hair.
Ideas?????

Hi,
I can't find any D7 model. If a DV7, gently use your fingers to widen the latches and put it down a bit, it should pop up otherwaie use a thin plastic to help it to pop up.

Memory Slots on 15" Powerbook?

I have a 15" Powerbook (1.25 mhz). According to the System Profiler there are 2 256 of ram sticks for a total of 512 mb of ram. Are there two available slots on this machine so if I want to upgrade the memory I'd have to take out one of the ram sticks?
Finally, any recommendations on where to buy a ram upgrade (cheapest)?
Thanks!

Hi DH --
Yup, you've got two memory slots, each of which can hold 1GB of RAM, for atotal of 2GB RAM. You'd have to remove one of your 256MBs to replace it it with something larger.
My advice (and that of many others) is not to go for the cheapest RAM, necessarily, but rather with RAM that's know to work with PowerBooks, as they can particular about the RAM the work well with.
I've seen crucial.com recommended highly here, and I personally like the Samsung memory used by Apple in its factory offered by OWC: http://eshop.macsales.com/shop/add/6205/OWC27SAMSO1GB/
Wherever you end up getting your RAM, make sure you get a lifetime warranty in case it ever fails so you can repalce it gratis, and also make sure the dealer's reputable and will around should you need to avail yourself of that warranty.
Good luck!

Memory slots on T530

I was wondering if both memory slots were easily accessible on the bottom of the unit. I looked at the guide but was a little unsure whether it was one or two under there. I remember years ago they were under the palm rest if not mistaken. I was hoping someone could clarify that for me.
Solved!

IMac Memory slots

I keep getting confused on how many slot there are total, so my question is, how many total memory slots are in the new intel iMac 24"?

flexibility of easily adding more memory in the
future, keep two (sic) memory slots open by selecting
the 1 SO-DIMM (rather than 2x512 SO-DIMMs) option.
Interesting to note, that this statement is only on the 24" model. It is absent from the 17" and 20" which only states:
How much memory is right for you?
Choose the standard 1GB of memory if you'll be photo editing, gaming, creating illustrations or building complex presentations.
The 2GB option is ideal if you plan to use your system regularly for sound design, video editing, DVD authoring, animation and intensive gaming.
Max out your memory with the 3GB option to enjoy the highest performance for everything you do.

Power pc G5 2004 dual 1.8 memory slot repair or re soldering help .

Hi I have a problem with my motherboard with slots one & two . I ran apple asd and the test told me its got a bad slot in them it also booted to 1 gig of ram for some reason . My last motherboard did about the same thing . I have a apple dual 1.8 processor a 2004 model . Its got 4 dims slots in if it helps you understand what Im talking about . well slots one and two are bad , but it I reboot it osx will see the ram as 2 gig of it . So Im thinking its got a problem with some lose solder joints in slot 1&2 . Can I resolder those joints . I understand it got lead free solder in it thats why it not making contact very well after some time of use .I was told that lead solder is better for them . I hate to take it apart again just to repair the bad solder joint . If you know of anyone on this board that repaired the memory slot on the main motherboard let me know.

Replacing the solder is a lot (emphasis on "a lot") more difficult than reflowing the solder.
If you are asking here on how to do something that you intend to sell, then I dare say that your technical skills may be inadequate for the venture.
Needless to say, solder application by hand would require a high degree of skill.
It is not the lead free solder, per se, that is the issue.
It is the lead free solder of the era and the character that allows a brittleness to develop over time. This when combined with constant expansion and contraction causes the fractures in the solder and BGA that create the connection issues.
When it comes down to a "nothing to lose" proposition, a DIY repair (or attempt) for self use using the described methods is more than adequate.
One pro company that does reflows (Golytronic) does just that, reflow. They don't replace the solder.
They also use commercial ovens, and even then, things don't always work out.......
BTW, the multi heating cycle of the solder is that which helps to give "elasticity" to the solder.....
Just so that you understand me, I dare say that I have overly simplified a fairly technical process.
I DO NOT endorse this information for commercial purposes.

Replaced my HDD on iMac (9,1) and screw of memory slot grille is useless. How to replace it?

My original iMac drive was slow & would sometimes not show at all (Some other of my drives would have to be used as Startup Disk) so I decided to replace it. I bought a 4TB HDD from OWC & proceeded with the installation. Couldn't beleive how much dust was in there!
After replacement, when I went to close the bottom grille—the one which gives access to the memory slots—I found the screw had its head slagged & I couldn't make it turn. I need a replacement, but can't find it anywhere.
Anybody?

Tale the grill cover into an Apple repair station. I'm sure they can replace either the cover w/screw or the screw.
